I'm not sure if we have any memcached experience on the list but I thought I'd ask. Can anyone explain this:
Notice how memcached1 has a much higher hit rate and memcached2 has a much lower hit rate?
The time for memcached1 is 5x less than memcached2 being up. That can have an effect on caching as right after a system comes up its rates are usually much higher and then over time fall off (iirc). I think it would take bringing both up at the same time to figure out if there is a true disparity over caching.
I thought that exact same thing :)
memcahed1: STAT uptime 9143 STAT get_hits 311736 STAT get_misses 11255
memcached2: STAT uptime 9144 STAT get_hits 49679 STAT get_misses 11116
Now that shows something not kosher. My guess is some app is not talking to both? What apps use memcached for what?
