Subject RE: Upgrading Tomcat
Date Thu, 01 Dec 2005 21:44:30 GMT
Actually one of the benefits I could see in reguards to using OpenSSL
for SSL in tomcat is the ability for OpenSSL to hand of the encryption
to a hardware acceleration device.  We have that set up in front of some
of our installations that have Apache frontending tomcat clusters using
the AJP connector. 

We had to do this because with a high volume of traffic going through
the box running apache load balancing, the CPU was bogged down doing
encryption/decryption instead of doing the load balancing between 12 or
so tomcat servers so throughput performance suffered.  Once we hooked
mod_ssl into a hardware accelerator card the CPU was free to do it's
usual load balancing tasks.

Although there seems to be limited availiablity of SSL cards that are
supported for Win32. If anyone has had luck configuring this set up and
has an SSL accelerator card they recommend please feel free to let me
know.

The same architecture change that allows tomcat to serve static content
quickly (the APR native connector) also allows Tomcat to use OpenSSL
instead of the JSSE for SSL which should improve performance.

I have been trying to get it configured using Tomcat 5.5.12 (native APR
connector) for the past few days and have hashed out a process with a
few other peeps in the list to configure it, but there are still a few
small details that need some clarification.

Thanks for finding this link.
Beside the explanation on various packages of TOMCAT, the message in
there also suggests that it is not worthy to use APACHE on a top of
TOMCAT due to TOMCAT now is handling static pages almost as good as
APACHE. 
But what about handling SSL - somewhere I read that APACHE handles
encryption much better than TOMCAT.  Is it still true?

It's here:

It did in 5.0, does not in 5.5.

No.  See the referenced e-mail.

> - does "Core" include the Embedded bundle? If not, what does it do?

No.  See the referenced e-mail.

I never use the .exe since it's missing the .bat (and .sh) scripts,
which are useful for debugging.  See the referenced e-mail.
