Just thought folks might be curious. We launched memcache to cache some
conf files a few weeks back, and today I figured out how to get some what I
thought were interesting stats back.
We have three boxes with up to 2 gigs of ram dedicated to memcache on each
box. The boxes are dual Xeon 2.80GHz boxes with 4 gigs of ram.
Those boxes get hit by around fifty web boxes, each getting around twenty
hits per second
Today I found that the avergage host averaged the following
bytes => 389,591,759
current connections => 870
curr_items => 620,316
Per host, per second, we are doing the following
Gets => '431.564115091378'
Sets => '0.54893441080739'
The average uptime for each process is 19.7 days.
The load on the boxes was right around 0, like 0.03.
To be honest I was a little concerned when we launched. I ran some tests
and hoped things would be fine, but launching something and introducing a
new dependency and possible bottleneck made me a touch nervous. But I think
as the above stats show, happy day, all is well. I almost think one box
could handle it all, but the redundancy/remap is nice to have.
