I just mentioned this on IRC as well, but I'll note it here.
We were just having issues with this on the site I work for (~3,000 unique
visitors per day) due to a high amount of anonymous traffic and getting
spidered (mainly by the Twiceler bot from the Cuil search engine).
http://drupal.org/project/boost
I installed that module and blocked twiceler and loads came down from server
choking ~5 to ~20 range... and have held steady at around 0.6 now (on a 2
cpu system).
Basically you're removing all those page loads from having to hit php or the
database which removes a huge load. Registered users still see the live
pages, and pages update automatically in the cache when you post an update
etc.
Hopefully this could remove enough of the server load to get performance
back to normal as it did for us?
Our loads over the past several days (copy/paste from an email to my boss):
-----
Where the load has been for the past few days:
top - 23:40:43 up 217 days, 21:21, 1 user, load average: 13.63, 9.82, 6.36
top - 12:24:06 up 218 days, 10:05, 3 users, load average: 12.46, 8.40,
5.90
top - 23:51:14 up 218 days, 21:32, 3 users, load average: 5.88, 4.41, 3.55
top - 06:14:40 up 219 days, 3:55, 3 users, load average: 19.65, 15.08,
8.83
top - 07:17:31 up 219 days, 4:58, 3 users, load average: 17.58, 10.67,
6.56
top - 02:15:24 up 219 days, 23:56, 3 users, load average: 11.59, 12.69,
10.01
top - 05:19:07 up 220 days, 3:00, 3 users, load average: 19.80, 13.73,
7.99
top - 05:29:08 up 220 days, 3:10, 3 users, load average: 2.56, 4.77, 5.92
top - 07:06:02 up 220 days, 4:47, 3 users, load average: 3.27, 3.01, 3.48
top - 08:32:16 up 220 days, 6:13, 3 users, load average: 9.69, 7.98, 5.60
top - 09:25:02 up 220 days, 7:06, 3 users, load average: 5.44, 4.53, 3.76
Where it is at the moment since installing the Boost module etc:
(still coming down hopefully, as you can see from the load averages (the
three load numbers from left to right are the load 1 minute ago, 5 minutes
ago, and 15 minutes ago))
top - 10:02:13 up 220 days, 7:43, 3 users, load average: 0.29, 1.08, 3.49
top - 10:06:04 up 220 days, 7:47, 3 users, load average: 0.58, 0.81, 2.84
top - 10:10:16 up 220 days, 7:51, 3 users, load average: 0.42, 0.56, 2.24
top - 07:40:51 up 221 days, 5:22, 1 user, load average: 0.24, 0.46, 0.48
Basically I want to keep the load around 1 or less if possible. Anything
over 2 (meaning both CPUs at 100% use) starts to inhibit performance on the
site and users start noticing lag etc... as the load goes higher the site
starts to error or become completely unavailable.
