Hi André Our server is handling around 20 requests per second. Please note that this is not a single site. There are many sites that are hosted on this server. As requests to host new site keep coming in, we keep reloading the virtual host config through a graceful restart. Here are my KeepAlive settings: KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 15 Unfortunately, I can't answer why the MaxRequestsPerChild was modified as it was done by the earlier sysad and there is no documentation left around by him. I have been reading up a few articles on tuning the apache performance and am planning to change them as per the requirements of the server. Please let me know if there is any other config/statistics I can provide which will help in debugging the issue.
There are 2 things I would do first of all :1) try to get an idea of the time needed, on average, to process 1 request. You can get this in the access log, with the parameters explained here :
http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats (%D parameter) (While you are at it, also add the %k parameter, it will be useful) 2) change the following setting : KeepAliveTimeout 15 to KeepAliveTimeout 2 and look at the results.Subjectively, I have the impression that the number of Apache processes (MaxServers 1024), is a total overkill for 20 requests/seconds, unless your requests take a very long time to be serviced.
But we'll see when there are some numbers. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
