Re: Benchmarking gcj-built Tomcat

There were small differences under different loads - but the garbage collector seemed like the biggest factor ( GCJ performed worse on JSP pages where more objects were created if I remember correctly ). Do you still have the benchmark code around? I'd love to see it... The amazing thing was the startup time - almost 0 ( it felt more like apache :-). It does start up fast :) The compiler we're using has a funky experimental optimiser (the same as used in the fast free eclipse project), and the startup became perhaps twice as fast when I switched from gcj 3.3. It compiles JSPs pretty fast too. That's one reason why I'd like to benchmark it. BTW - GCJ is not a virtual machine and doesn't have a JIT - it is a ahead-of-time compiler, just like C and C++ compilers. This may have been true a while back, but it isn't now -- gcj can interpret bytecode just like any other JVM. In my Tomcat package this is exactly what it does when executing servlets (everything else is built to native code). You're right in that doesn't have a JIT though. The biggest problem at that time was dynamic class loading. GCJ has a small interpretor and could load servlets - but the difference in performance between precompiled code and interpretor was significant. It probably still is, though not as bad. But it's not such a big problem as it seems, as most of the calls that a given servlet makes will be to native-compiled methods.

Benchmarking gcj-built Tomcat
Hi all, I've been working on building Tomcat and its dependencies to native code with gcj, and I'm interested to see how it compares against Tomcat running under a 'normal' JVM. Now, I'm well aware that benchmarks are not a real-world indicator of performance, but I don't have any particular web application to test and I was wondering if anyone has a benchmarking suite that they can point me at. In case you are interested in the gcj-built packages, they are available at http://people.redhat.com/gbenson/naoko/ as source rpms and as binary rpms compiled for Red Hat Linux 9. Everything except the webapps is compiled to native code; the webapps are basically unmodified and are interpreted just as they would be with a normal JVM.

Is it purely and interpreter or does it do some jit'ing? As far as I know, it's just an interpreter, but I may be wrong. However, any calls to native-code stuff will execute as native code so it's perhaps not quite as bad as it may seem.

[PATCH] mod_webapp tweak
Hi, I've tripped over the 'you need to set a ServerName before you configure mod_webapp' a couple of times in the past so I had a go at fixing it. The stored hostname and port number are only used for informational purposes, and the attached patch makes them optional (they get replaced by '*' wherever used).
