Hi,
Looking at the apache doc, the default cache removal algorithm is GDSF. Since there are different variations of this algorithm can someone confirm which variation Greedy Dual Size Frequency apache uses ? That is, what is the value of cost ? Does it give preference to hit ratio or try to
Works now...Thanks for the help...

Hi,
I have configured apache to run using the worker MPM. I am trying
to restrict the number of child processes it spawns to one.
Here is the relevant section from httpd.conf
IfModule mpm_worker_module
StartServers 1
MaxClients 150
ThreadsPerChild 150
MinSpareThreads 1
MaxSpareThreads
Thanks Joshua. I am trying to make sure there is exactly one memory cache per box. Guess your explanation means that I am achieving that with the config I posted ?
Also, would setting the ThreadsPerChild to 150 cause performance issues( I am running Apache on Red hat) or is 150 a OK value ?
Hi,
Is there a way to log the time taken to process a request in milliseconds precision ? The documentation for %T says it can only logs the time in seconds.
Thanks in advance,

I found the problems with mod_mem_cache under load. I am going to look into mod_disk_cache as per your suggestion. I hope mod_disk_cache does better. Thanks for all the help, Joshua.

Hi,
I have an Apache 2.2.2 setup on a Redhat box. Caching is implemented using mod_mem_cache.
Apache was built to use worker MPM. Here are the relevant sections from httpd.conf
#
# mod_cache/mod_mem_cache settings
#
IfModule cache_module
IfModule mem_cache_module
CacheEnable mem /
Thanks Joshua for the quick reply. Guess this means using mod_mem_cache will not give me the best cache hit/miss ratio as compared to mod_disk_cache ?
Is the way I have configured apache wrong ? Is it possible to run only 1 instance of httpd on a box to maximize the cache hit/miss ratio ? Would
Thanks Joshua. My apache setup talks to tomcat using mod_ajp. One last question on the behavior of Apache. Say, there is a page that is in the cache which has expired. A client makes a request for that page. Apache looks in the cache, finds that the content has expired so contacts tomcat to fetch
