Once again today, someone is complaining about page load time on the pump. I am beginning to suspect that this is a bandwidth problem.
It is sooooooooo not bandwidth.
Typical usage is 50-80 k/s each on larousse and pliny. (Usage is a touch lower on larousse, which serves the English wikipedia, because it's set up to compress cachable pages that are sent to non-logged-in users for about 25% total savings; and also pliny carries the big database backup downloads.)
I've gotten ca 1000 k/sec downloads of backup dumps from uni here, even when the wiki was hella slow.
If you'll look at: http://www.wikipedia.org/stats/usage_200307.html you'll see that peak usage does not exceed average by that much.
What has been done to investigate the reason behind this problem, and what were the results of said tests? I haven't really heard a straight answer from anyone saying what the problem is, just speculation.
When I stare at mysql's process list to see the slowpokes, who comes up on top?
Search, search, search.
