RE: Tomcat 4.1.x Vs 5.0.x
From personal experience in testing on Suse 8.2 and tomcat 4.1.30 using a load of 1000 concurrent connections pulling continuous pages from the webserver, the following was found: - using ibm jdk and blackdown jdk (basically same thing) gave the fastest serve times for the first hour of testing. unfortunately the serve times slowed drastically after 1 hour under load. - sun jdk server time results remained the same under the load for the length of the test (5 hours) We concluded the sun jdk was best for our environment. However it can be concluded that the ibm version is good if you do not need to handle that much load. -joe - Original Message - From: Shapira, Yoav [EMAIL PROTECTED] Date: Wed, 12 May 2004 15:31:37 -0400 To: Tomcat Users List [EMAIL PROTECTED] Subject: RE: Tomcat 4.1.x Vs 5.0.x Hi, Sun 1.4.2 IBM 1.4.1 Bea 1.4.2 (JRockit) Which one would be better?

RE: Tomcat 4.1.x Vs 5.0.x
Hi, Is it better to use Tomcat 4.1.x or 5.0.x for such scenario? Which version is faster and stabler? The tomcat 5.0.x versions are faster and at least as stable. Will applications designed for Tomcat 4 work fine with version 5? Applications designed for the Servlet Specification will work fine with tomcat 4 and tomcat 5. Applications whose designers were bad enough to include tomcat 4 - specific code will not work with tomcat 5 obviously. What is the recommended JVM for production use on Linux? Sun or IBM? Which version? Again, the latest stable version is what you want. We have people using Sun, IBM, Blackdown, and JRockit on this list. To answer one of your other questions: the typical hardware requirements for tomcat would be any old processor and 64MB of RAM. This varies greatly depending on the user application's memory and CPU needs.

I find Sun to be the better of all the JVMs I have tried in both cases: performance and stability. If someone can show me something working and prove their points, then I'll have reason to believe, but from my own experiences Sun's VM is usually less buggy and runs very well and the others including IBM and Blackdown don't really compare (at least on Intel and Linux anyways).
