I am using pcre memcache module as the client with a apache+prefork setup, on the client side it is also about 2000 requests per second (i.e. 1 memcached get per request). It is roughly full loaded but I don't think is heavy.
Memcached is deployed on another server, the problem is it is deployed as <100 separate instances, each serve some kind of the requests. There might be some context switch overhead and we are thinking about merge them together next. There is no swapping. The network should be OK because they are connected by a router with Gigabytes bandwidth but we actually use Megabytes currently. -- Best regrads, Congwu On Fri, Jul 9, 2010 at 2:43 PM, dormando <[email protected]> wrote: >> Hello, >> I have a server that roughly have 2000 hits per second on >> memcached, I have seen >> about 0.06% GETs got response time higher than 10ms, is it >> something expected? > > http://code.google.com/p/memcached/wiki/NewPerformance > > that's probably packet loss, system swapping, or your box is otherwise > overloaded. also depending on how you're measuring it your client box/etc > could be slightly broken. > > -Dormando >
