Hi Lesly I don't know if you have ever watched how they balance a car wheel, but if not. They bolt it to an electrical motor and spin it around. There is sensors on this motor that detect where weight needs to be added to get the wheel balanced so it wont vibrate when driving above 100km/h. What I am trying to say is that you can't balance the wheel without spinning it. You can't tune your server without knowing the type of traffic and volume it process. Before you start tuning start to gather some graphs and statistics about your webservers. This will enable you to make sensible decsisions about what to tune. I can't really comment on tuning apache php because I dont use it very often. A start would be to analyze access logs and see what your avarage response time is. If you see signifcant spikes drill down into those and try to acertain what is causing them. Does the php connect to a database if it does, have a look at the database statistics and slow query logs to see if you can do any optimizations there. Typically better indexes or rewriting queries or forcing a query to use your "plan" instead of the database plan for the query. If you are using tomcat I would recommend using modjk to interface between apache and tomcat. We use apache mpm because this allows us better scalability. We tune various paramters such as: ServerLimit ThreadLimit StartServers MaxClients MinSpareThreads MaxSpareThreads ThreadsPerChild MaxRequestsPerChild Giving you values will not make any sense as it is very application specific. Our tomcats does not "interact" with users via jsp which in many aspects makes it easier to tune. We have an "application constant" which is a measure of how many concurrent requests we can process on a tomcat server. We determined the constant using jmeter and lots of testing. If there is quick fixes then I don't know them, I am sure there are some easy wins you can apply but a bit of googling should reveal that. If you want your server to work very well you need to put in the corresponding effort. while true do begin research measure implement analize end Best Regards > -----Original Message----- > From: Leslie Herps || Novacle B.V.
