mod_mem_cache: Requests: 35000 Time: 54.90 Req/Sec: 637.81 no cache: Requests: 35000 Time: 54.86 Req/Sec: 638.81
The above result would suggest that mod_mem_cache isn't being used in this case. It could be that mem cache has decided not to cache the requested file for whatever reason, which is being served via the normal "no cache" path.
It'd help if I compiled mod_mem_cache in. *duck* (We need better error messages when the cache type isn't found! Can't we error out at config time?)
Anyway, mod_mem_cache yields (after bumping up MCacheMaxObjectSize to 100k):
Requests: 35000 Time: 40.99 Req/Sec: 856.73
That brings it in line with mod_disk_cache in maxing out my network. Time to craft some better tests or find a faster network... -- justin
