The reason for this is probably that the windows version of Sun's JVM is set up with defaults for memory sizes and garbage colletion algorythms which are optimised for a desktop pc, not a server. All of these options can be changed manually, and a true comparions can only be made where both instances are set up with the same values on the same hardware. At a simple level using -server on both will narrow the gap, but only a good knowledge (and a refrence book) will ensure that the two things are the same. You should tune your server processes, and refine your applications, according to the resource use that you measure in tests and in the wild. I'm sorry I don't have a refrence for you to look at, but you might like to look at my slides from apacheconEU06 at which I talked about Garbage collection tuning. d. ******************************************************************************************************* The information in this e-mail is confidential and for use by the addressee(s) only.
