Subject Re: Servlet/JSP Slow Startup
Date Mon, 14 Apr 2003 12:09:56 GMT

Windows 2000 alone will use approximately 128-180 MB just sitting there.  
So, by using those options, you told the JVM to allocate a minimum of 128MB 
to Tomcat, which doesn't exist unless the operating system starts swapping 
to disk.  Add in the (relatively) slow processor which would also indicate 
a slower bus and a slower memory bus, and you have a recipe for a slow JSP 


- precompile your JSPs if this is a production server

- increase the amount of RAM

- stop using the Xms and Xmx options and let the JVM and OS work it out
