It uses the Java compiler for activities such as compiling JSPs into Servlets
into Java class files.
All versions of Tomcat require the JDK.

If each request is handled only by a single thread then it should be expected
that a CPU with 1/2 the speed performs 1/2 as fast.

Is the database also running on a VM? My experience with "problematic

In general, it is technically possible for a 32-bit application to perform
faster than a 64-bit application when running on a 64-bit CPU because of CPU
memory cache behaviour.
64-bit memory addresses occupy more space within a single cache line and can
result in added memory cache misses (cache

GET and POST are HTTP verbs/operations.
It is impossible to have a combo GET/POST. Which ever verb is specified in the

You could also check "top" to see whether the CPU is being consumed in usr or
sys space, along with whether maybe the memory on your system is maxed out
(trigger high CPU load transfer data between RAM and swap space).

Howdy,
First, to clear an incorrect point made...
There is a point of switching back to HTTP after HTTPS. From a server load
perspective having to perform SSL computations for every single HTTP request
can be a serious performance bottleneck. As for the security aspect,

Hi again,
I thought about this a little more and I think what you're experiencing might
be as a result of the RequestDispatcher.
When the RequestDispatcher "fowards" to a URL resource, it overrides the
SSL/Authentication constraints you have setup. There is a way of getting
