| up_the_irons | not sure
what makes a big difference is disk I/O | [00:00] |
| jeev | i mean while building
if i vi /etc/rc.conf for example on another terminal it would lag. | [00:00] |
| up_the_irons | single drive vs. 8 drive RAID 10 w/ a 256MB cache, I'm always going to win :) | [00:00] |
| jeev | i would see considerable lag in certain places even for make installkernel or installworld
it's that ccis shit hmm HP Smart Array P400i with 256MB read cache | [00:00] |
| up_the_irons | ccis? | [00:01] |
| jeev | 2x72 gig sas 10k | [00:01] |
| up_the_irons | 10K, not bad
the RAID controller / firmware can make a huge difference too | [00:01] |
| jeev | -rw-r--r-- 1 root root 5271367680 2009-11-04 00:02 disk0.qcow2
hmm maybe if i just have a raw image rather than something that expands | [00:03] |
| up_the_irons | 3ware 9650SE-8LPML (what I have) with the latest firmware that introduced some wicked "read intelligent cache" stuff, is like twice as fast as my older ones | [00:03] |
| jeev | i just dont get the bog
or lag | [00:04] |
| up_the_irons | jeev: how long are you expecting make kernel to take? | [00:04] |
| jeev | a minute or two longer than yours. | [00:05] |
| up_the_irons | i'm doing like 'vi /etc/rc.conf' and stuff, while building, i see no lag
oh, i should do a WHT benchmark | [00:06] |
| jeev | yea
benchmark doesn't score that bad on mine | [00:06] |
| up_the_irons | jeev: your raid controller seems a bit skimpy; and keep in mind RAID 10 will trump RAID 1 | [00:07] |
| jeev | true
i can try converting to raw and see what happens | [00:08] |
| up_the_irons | yep, that's easy | [00:10] |
| jeev | hm
all i know is that i shouldn't be seeing what im seeing are you running unixbench wht ? | [00:12] |
| up_the_irons | jeev: like, right now? | [00:13] |
| jeev | sure | [00:13] |
| up_the_irons | nah | [00:14] |
| jeev | ok, well i've gotta figure this out
for now i'm gonna pass out i feel like someone is microwaving me. | [00:14] |
| up_the_irons | haha | [00:14] |
| ballen | ballen turns off the microwave | [00:14] |
| jeev | heh
good night | [00:14] |

| up_the_irons | get a thinkpad | [09:15] |
| ballen | not a fan of Windows or really anyother OS than Mac on a laptop | [09:16] |
| up_the_irons | well, of course not Windows | [09:21] |
| toddf | my thinkpad t41 is way cool runnin OpenBSD ;-)
I removed the 'made for windows xp' sticker .. need to get a cd to put some openbsd stickers on it | [09:23] |
| up_the_irons | i bet
i have a microSPARC laptop running OpenBSD 2.1 and fvwm (yeah, I installed it *that* long ago) | [09:23] |
| ballen | heh
brb need coffeee | [09:24] |
| toddf | microSPARC eh? I have two tadpoles (one 3gs one 3gx) they're decent but heavy so I let them burn a small amount of juice in the server room | [09:28] |
| mhoran | up_the_irons: Hah, awesome. | [09:29] |
| *** | ballen is now known as ballen|away
ballen|away is now known as ballen | [09:41] |
| up_the_irons | toddf: yup, that's pretty much what I got, I think (3gs)
heavy as all hell and no working battery anymore | [09:50] |
| jeev | so up_the_irons
i wonder what i could do to find out why it's not performing right oh yea, convert to raw | [09:50] |
| up_the_irons | jeev: you try different setups, benchmark, and compare; it's really a brute force task
nothing magic | [09:51] |
| jeev | i wont install ubunti!
i think maybe cause i'm using a git version or something | [09:51] |
| up_the_irons | jeev: that's fine, don't install ubuntu; but the recipe is still the same ;) | [09:53] |
| mhoran | Gotta do the cooking by the book! | [09:53] |
| up_the_irons | haha
jeev: do this in one of your VMs: dd if=/dev/zero of=delete-me bs=1M count=1000 conv=fdatasync adjust count to be double your ram right now that file would be 1G paste results | [09:53] |
| jeev | double ram ?
i have 8 gigs so just 16000 | [09:56] |
| up_the_irons | jeev: in the VM
jeev: double ram of the VM | [09:56] |
| jeev | oh
k i just started it up with raw image dd: unknown conversion fdatasync | [09:57] |
| up_the_irons | jeev: freebsd eh? :) k, leave off "conv=fdatasync" | [09:58] |
| jeev | yea
how long does yours take? :D | [09:58] |
| up_the_irons | not very long
i did it in a VM with only 256 RAM | [10:00] |
| *** | ballen is now known as ballen|away | [10:00] |
| up_the_irons | $ dd if=/dev/zero of=delete-me bs=1M count=512
512+0 records in 512+0 records out 536870912 bytes transferred in 34.458263 secs (15580324 bytes/sec) | [10:00] |
| jeev | i see | [10:00] |
| up_the_irons | i got an 83 on the WHT test for that VM | [10:01] |
| jeev | i got a 63
gotta figure out why | [10:01] |
| mhoran | 83? That's pretty good, eh? | [10:02] |
| jeev | dd still running, ran dd on a non vm machine, opteron 37.5mb/s :/
yea it's good for bsd linux scores a lot higher opened up another connection, ls -l been stuck for about 15 sec | [10:02] |
| up_the_irons | yeah, my linux VMs are fast, esp. w/ the virtio block devices i just enabled ;) | [10:03] |
| jeev | damn | [10:04] |
| up_the_irons | jeev: 37.5 mb/s, is that on your host? | [10:04] |
| jeev | up_the_irons, on another box :)
it's only at 900 mb i'm gonna stop this man shit | [10:04] |
| up_the_irons | ok girl | [10:04] |
| jeev | what was the kill
sigalrt or some shit lol that makes dd post stats | [10:04] |
| up_the_irons | kill -usr1 <pid-of-dd> | [10:04] |
| jeev | ALRM | [10:04] |
| up_the_irons | USR1 | [10:05] |
| jeev | or usr1 yea
weird, it's killing it. | [10:05] |
| mhoran | up_the_irons: So the virtio stuff is working well? | [10:06] |
| jeev | didn't know virtio worked on bsd | [10:06] |
| up_the_irons | jeev: it doesn't | [10:06] |
| jeev | im just doing count=512 now | [10:06] |
| up_the_irons | mhoran: on linux, yeah; not sure i see any big performance increase, but maybe if there were like 30 linux VMs, I would | [10:07] |
| jeev | up_the_irons, what do you get on the host for dd
536870912 bytes transferred in 61.043277 secs (8794923 bytes/sec) host = 536870912 bytes (537 MB) copied, 0.921171 s, 583 MB/s | [10:07] |

| jeev | i see | [10:08] |
| up_the_irons | jeev: 512M is too small for an 8GB RAM host, you're looking at mostly cache there | [10:08] |
| jeev | you doubled the ram
ok trying 16000, wish me luck oh man that's too much though | [10:09] |
| up_the_irons | jeev: also, use conv=fdatasync | [10:09] |
| jeev | it'll take too long eh
should i just let it go | [10:09] |
| up_the_irons | jeev: try 8GB | [10:11] |
| jeev | just gonna let it go | [10:11] |
| up_the_irons | k | [10:11] |
| jeev | bbiab i guess | [10:12] |

:< not too great eh brb | [10:15] |
| up_the_irons | jeev: i'd say that is average-ish. get a 3ware RAID card in there with RAID 10 and RiW cache, and it'll go a lot faster ;)
by comparison, a Linux VM: dd if=/dev/zero of=delete-me bs=1M count=2000 conv=fdatasync 2000+0 records in 2000+0 records out 2097152000 bytes (2.1 GB) copied, 26.8445 s, 78.1 MB/s almost 80MB/s, pretty nice for a VM | [10:17] |
| ballen | vruoom | [10:18] |
| up_the_irons | lol, it's faster than the host!
2000+0 records in 2000+0 records out 2097152000 bytes (2.1 GB) copied, 27.937 s, 75.1 MB/s | [10:19] |
| ballen | that doesn't really make sense | [10:20] |
| up_the_irons | up_the_irons shrugs | [10:20] |
| ballen | maybe /dev/zero is faster in a VM
;-) i hate dreary grey fall weather | [10:21] |
| mhoran | mhoran loves it.
I realized today that I hate summer. | [10:27] |
| mike-burns | Yeah, I love this weather too. But I'm a native of it. | [10:30] |
| ballen | yea I'm in nothern michigan... theres no more colorful leaves, it rains and there is constant low grey clouds
i hate this part of the year I feel like I'm in a dim lit lightbox all day | [10:33] |
| toddf | up_the_irons: I had a local battery place tell me they could make a refurbished battery for around $90 once, something tells me this is not going to happen anytime soon | [10:33] |
| up_the_irons | toddf: hah
toddf: for all that whopping 85 Mhz, not sure if I'd do it either... | [10:34] |
| mhoran | Poor people ... always showing up for interviews on time.
Berklee time does not sync up with normal time. Ever. | [10:35] |
| jeev | hey up_the_irons
on raw, it built in 20 minutes >>> Kernel build for BOX completed on Wed Nov 4 18:37:09 PST 2009 -------------------------------------------------------------- real 20m56.486s disregard the fact that i didn't sync the time ;) | [10:40] |
| up_the_irons | "raw" ? | [10:40] |
| jeev | Supported formats: cow qcow vdi vmdk cloop dmg bochs vpc vvfat qcow2 parallels nbd host_cdrom host_floppy host_device raw tftp ftps ftp https http
yea for the img since i didn't set up lvm | [10:41] |
| up_the_irons | jeev: ah ok | [10:41] |
| jeev | i'm gonna go back to qcow2 and test that once more | [10:41] |
| ballen | I'd try out tftp | [10:42] |
| jeev | yea man i have no need to get additional hard ware
i'm not t4rying to compete with you, im just trying to get vm's going for myself | [10:42] |
| ballen | ;-) | [10:42] |
| toddf | up_the_irons: I have some sparc systems that are < 10mhz, a couple of vme bus ones too
jeev: I'd love to setup a vm system here, waiting on a c2t cable for an ibm xseries 355 I got for $40 (steal of a deal!) | [10:43] |
| mhoran | Great deal! | [10:44] |
| toddf | `here' being `at the end of a cox cablemodem, no chances of hosting, test lab style setup' | [10:44] |
| up_the_irons | toddf: $40? nice! | [10:44] |
| toddf | mhoran: and its a local place that buys stuff from auctions and by the pallette, I intend to frequent their place .. ;-) | [10:44] |
| up_the_irons | i think I still have a sparcstation 10 in my garage | [10:44] |
| toddf | I almost have more sparc(32) systems than I do i386 systems | [10:45] |
| jeev | 355?
aren't those old school? yea i remember iwas gonna buy a ton of those ibm's till i found out that it required a stupid cable | [10:45] |
| toddf | jeev: it has a xeon cpu and a 1U case, whether it is HT or 64bit remains to be seen, but it's a good deal regardless ;-) | [10:45] |
| jeev | free? | [10:45] |
| toddf | jeev: it was $6 on ebay | [10:45] |
| jeev | oh cool
yea i like those old school boxes, i have a lot at the datacenter | [10:45] |
| toddf | the cable, the system was $40 locally | [10:46] |
| jeev | oh
single cpu ? how fast | [10:46] |
| toddf | I need the cable to find out... | [10:47] |
| jeev | ahh | [10:47] |
| toddf | someone didn't leave it booting the cdrom by default or I'd have seen some activity on the serial port
it's on its way from china, should arrive this week or next | [10:47] |
| jeev | but those are older school ones
guaranteed to not have vme or vt whatever it is | [10:47] |
| toddf | vme? heh
how about 64bit capable? | [10:48] |
| jeev | i'd say 50 50
i've seen a lot that have been 64bit maybe those were 335's hmm | [10:48] |
| toddf | 8676-61X is the TYPE code fwiw | [10:48] |
| jeev | too bad they're not dells | [10:49] |
| toddf | 64bit but not yet VT capable, moof, ohwell, I'll take the 64bit | [10:49] |
| jeev | punch in their code
and get the exact specs well i think i got i got a xeon i can send yu if thats not 64bit i THINk if the ones i have are 64bit heh | [10:49] |
| toddf | easy test if you don't mind booting a 6mb iso
ftp://ftp.usa.openbsd.org/pub/OpenBSD/snapshots/amd64/cd46.iso | [10:50] |
| jeev | they're cpu's, not entire systems
;) | [10:50] |
| toddf | if the kernel loads and inits its 64bit capable, if it hangs after loading, its not
heh | [10:51] |
| jeev | no can look at the stepping and
cpuu or whatever thing its called the code it's not here with me i'll check later | [10:51] |
| toddf | one site says 'Intel Xeon DP' but that doesn't help me either | [10:51] |
| jeev | if you're really curious and anxious
take the heatsink off and read it ;) | [10:51] |
| toddf | that'd do it for sure ;-)
I'll do that later, have a few things piled ontop for now | [10:52] |
| jeev | i guess we'll see
bbib bbiab | [10:56] |

20 minutes aint bad | [11:47] |

if thje kvm port was working i'd do it | [11:51] |

you have any free disk partitions? | [11:52] |

i'm not sure what the perf diff between raw image and lvm would be; but if you're happy with raw image, keep it | [11:52] |

it doesn't need to grow | [11:55] |
