James would definitely benefit from the more aggressive garabage collection provided by -server.
One of the performance issues we looked at a while ago was an out of memory exception when mail is received at a very fast rate, it seems to be related to a build up of garbage over a period too short for the gc to step in, and where the load is high so that a higher priority gc might be required in order for it to get enough clock cycles to beat the memory consumption. Its Catch-22, when the server is busy where should the balance between not running the cg and running it be. It was my belief that this would have been solved by the use of -server. Also incremental garbage collection, which I still havent tried. d. > -----Original Message----- > From: Rinne Ville [mailto:[EMAIL PROTECTED]] > Sent: 14 January 2003 12:40 > To: 'James Users List' > Subject: RE: Hotspot server switch > > > Hi, > > Have you done any performance testing etween the different vm's ?
