HOW TO: How do I allocate memory in JVM for extra virtual hosts

2002-09-27 Thread Donie Kelly
Hi all I am running tomcat 4.0.1 with virtual hosting and was wondering how much memory to allocate to each additional host. By default, we use 64M for one host but adding another 64M for second host seems excessive considering it's the same tomcat instance. However, if we add a lot the JVM will u

Check out perc 3.3 at http://www.newmonics.com/info/gc.shtml, it has a pretty decent GC performing much better than Sun's. Also IBM's JVM is pretty good too. -Original Message- From: Brad Plies To: Tomcat Users List Sent: 9/27/02 12:18 PM Subject: Re: HOW TO: How do I allocate
