Holy crap, Brendan Gregg's site went down. Proof he is human I guess?
10:36:09 up 34 days, 20:05, 1 user, load average: 2.39, 2.34, 2.08And yes I'd noticed on many *nx systems that it didn't seem to be pure CPU (I think I once had a single-CPU SunOS 4.1.1 NFS server report into the tens or hundreds because disc was slow) I've mainly been treating it as if CPU for ~30Y. Goodness knows what I might have tuned better!
Thank you!
(network card load is one of the next metrics I check next if load average and wait%/user% etc aren't telling what's wrong)
Just because we can deploy services that can take a million RPS doesn't mean we have our side projects / hobby sites in order, hah. I worked in hosting for a long time and I had a personal WordPress site which would get hacked every other month. I literally fixed that problem daily at $JOB, but couldn't be arsed to do something better for myself. It worked, and it was quick and easy. The point was the content.
These days, I'd just use something like Medium or Tumblr. Let someone else worry about hosting it :)
PS: yes this is meant to be a compliment on the prolific output on performance related topics that Greg puts up on his page.

(I made that in response to a similar comment back then...)
Also wow, what a time capsule that picture is in terms of office style and computer hardware.
It seems like such a waste to have it scattered all over the place, and for all the author's hard work in tracking it down to go to waste.
