I mean you test is excellent, but you can't compare this two different cache-types. The remote-cache is always slower! But when you save the cache-files into the local machine and this machine is very, very slow (too many requests) than is the remote - machine a lot of quicklier with the same cache-save-type. Hey,

I could not resist to appreciate the blog. Being a NewBie I have a question. -> Could you suggest what is the best alternative to memcached for session clustering which would integrate seamlessly with the older versions i think thatGreat Blog !

I'm not sure about hardware characteristics of the server (certainly not outdated). Results are lower which is normal for server that is on live production and loaded. I got this as results. ----------------------------------------------------------------------- Object cache - Iterative execution of object property getter 244908 req/s eAccelerator - Iterative execution of $cache->load() method 45681 req/s MemcacheD - Iterative execution of $cache->load() method 1989 req/s Query cache: 806 req/s Query with caching disabled: 579 reqs/s Does anyone have some numbers on real distributed server architecture. Are there some optimal performance numbers to compare with as some minimum to care of when comes to the cache performance. Thanks in advance.

Object cache - Iterative execution of object property getter 244908 req/s
eAccelerator - Iterative execution of $cache->load() method 45681 req/s
MemcacheD - Iterative execution of $cache->load() method 1989 req/s

Does anyone have some numbers on real distributed server architecture. Are there some optimal performance numbers to compare with as some minimum to care of when comes to the cache performance.

Thanks in advance.

It would be nice to see the performance if you try few tests with parallel execution of 2 or 4 or 8 processes/threads on client side or multiple computers for tcp oriented tests.
