Some network benchmarks

I wanted to see how fast my rack is. Now, I think that one of my shares is doing a bittorrent at the same time, so this is a conservative test. For most of these, I’m doing a wget of the Rochester Road Runner speed test file at http://speedtest.rochester.rr.com/testlarge.zro

  • From RR.com to my home machine: 19:12:13 (392.85 KB/s)
  • From RR.com to my rack: 19:02:44 (493.74 KB/s)
  • From my rack to my home machine: 20:00:30 (364.74 KB/s)

(Yeah, I know the times and the given KB/s values don’t make sense. I just report them as wget reports them.)

That’s not bad. I think it shows that the rack system can keep the 10BaseT network connection pretty saturated. Both up and down.

That’s a rack!

I put my server on the rack today and xen1.xcski.com is open for business. I’ve already moved the Rochester Flying Club and Rochester Association of Family Mediators web sites over. As the DNS changes propogate, I’ll be able to remove the ones on the linode.

It appears that mail is working on the new site as well, so I’ll move the mailman mailing lists over pretty soon. I’ll probably move this blog over there as well. Then comes the hard part – moving the navaid.com application over.

The only sour note is that when I started up the rack, one of the quarter share xens didn’t want to come up correctly. It complained about tons of fsck errors, and I decided to just wipe it and re-install it. I hope that doesn’t happen again. One thing I noticed is that the xen kernel doesn’t have the ext3 module compiled in, and so it’s mounting these file systems without journalling. I’m going to have to fix that.

Ow ow ow ow

I had peridontal surgery this morning. Evidently my bad habit of sticking sharp things into the gap between my upper front teeth has caused the bone to erode to dangerous levels. They cut away the gum down to the bone, scraped away accumulated crud on the bone, applied something to make the bone grow again, and stitched it back up. It wasn’t all that bad while it was going on, except the novocaine made my nose numb. But now it’s done and the novocaine has mostly worn off. And I’ve got the pain you’d expect from having your gums cut open and the bone scraped, plus the stitches are irritating the inside of my lip. The pain killer they gave me is making me feel bleary and very sensitive to movement, and doesn’t seem to be doing anything about my mouth. And I can’t eat anything that involves “incising” with the front teeth for two weeks.

This is less fun than I thought it would be.
