Subject AW: Benchmarks: Catalina M5 vs. Apache 1.3.12
Date Tue, 05 Dec 2000 20:25:14 GMT

The notion of "tomcat is fast enough" used to be a dream but we`re
getting there.

I am going to run a few big sites on a combo of apache and tomcat, since
there are a lot of PHP and mod_perl scripts in use. That means that for
a given period of time Apache needs to sit in front of Tomcat to do
a lot of work. This amount of work gets smaller and smaller during
a period of about 12 months. Plans are to shift slowly to Servlets/JSP
only, buts its not easy to get the right programmers for that purpose.

In this timeframe we hopefully will see further improvements in regards
to stability and performance of tomcat. And i personally hope that
the unofficial battle between all the versions of tomcat (3.1, 3.2, 4.x)
will improve the overall quality of Tomcat but finally end up in just one

Tomcat is already the only server for the intranet application server
which runs an publishing/content management system. Here we see an
performance of up to 25-35 request/s (500 MHz Pii, Suse Linux, 512 MByte,
IBM JDK 1.3)
including an XML-RPC protocol, which is reason for quite an hefty overhead
but its worth it.

The real server will have an 1 Gz CPU and 1 GByte of RAM so i expect some
possible request/s.
