Hello Peter,
There is no JVM/platform that is clearly faster than everything else in every
aspect, they have different streghts and weaknesses.
However, for a J2EE based application I guess that you are not very interested
in graphics performance, but rather thread performance, I/O performance, memory
management and general scalability. Being a J2EE server vendor, we regularly
test many different Java Virtual Machines from our server's perspective and our
testing indicates that you should try JRockit (http://www.jrockit.com).
It provides a very lightweight thread implementation as well as very good I/O
and memory management which makes it scale better than anything else we've
tested. It also does adaptive optimizations, like Hotspot, and it supports J2SE
1.3.
It is only available for windows so far but I hear that they have betas coming
out soon for Linux and Solaris.
However, you should download different VMs and try them with your application
before deciding.
Regards,
Karl Avedal
