We're also using TC 3.3 on our production systems and are switching to TC 5.5.
The memory penalty is real but you'll be using up to date and actively maintained stuff with TC 5.5. Also you could try to reduce the AJP13 / HTTP 11 threads and remove some JMX Listeners 2006/4/19, Abhi Karmos <[EMAIL PROTECTED]>: > > Hello all, > > Sorry, could not find an answer on tomcat-users. > > We run tomcat inside an embedded system and we are planning to upgrade the > tomcat version from 3.3.1 to 5.5.16.
