I got more memory for my server; it has 512MB now and the memory utilisation has this profile:

I've tried to enable mod_cache in Apache2 config files but I'm not sure it's
working, since /server-info gives me this info:
- Module Name: mod_cache.c
- Content handlers: none
- Configuration Phase Participation: Create Server Config, Merge Server Configs
- Request Phase Participation: none
- Module Directives:
- CacheEnable - A cache type and partial URL prefix below which caching is enabled
- CacheDisable - A partial URL prefix below which caching is disabled
- CacheMaxExpire - The maximum time in seconds to cache a document
- CacheDefaultExpire - The default time in seconds to cache a document
- CacheIgnoreNoLastMod - Ignore Responses where there is no Last Modified Header
- CacheIgnoreCacheControl - Ignore requests from the client for uncached content
- CacheIgnoreHeaders - A space separated list of headers that should not be stored by the cache
- CacheLastModifiedFactor - The factor used to estimate Expires date from LastModified date
- CacheForceCompletion - Percentage of download to arrive for the cache to force complete transfer
- Current Configuration:
Current Configuration is empty!
I'm using the config suggested by Stefane Fermigier early in this thread.
I've disk cache since the respective directory is populated by apache2 by I'm not sure
about memory cache.
Is there anything else I could do to improve the performance, or to benchmark it so I
can compare to see if there is room to improvement.
Thanks for any info.
