Using tomcat as standalone

[balachandra maddina <ch...@gmail.com>]

Hi There,

  Im wondering what are the performance implications of using tomcat as
standalone? many suggested to use the tomcat along with IIS. but im not sure
why is this required? could somebody help me on this please.

Thank you,
bala.

Front-ending Tomcat with IIS would create a lot of extra overhead and administrative workload - don't do it unless you're already using IIS as your primary web server for the domain of interest.

Tomcat does very well at serving static content by itself these days (better than IIS).  If you're using SSL and have stringent performance requirements, consider installing the APR native library with Tomcat; this uses OpenSSL rather than the Java libraries and is noticeably faster.  APR may get you a performance improvement for non-encrypted requests as well, but you'd have to measure your webapps with it to be sure.

Use the latest Tomcat (6.0.20) and JVM (6u14) in server mode for the best performance starting point; use a 64-bit version of the JVM if you need the heap space and your platform supports it.
