Subject Performance problems on larg pages with taglibs and includes
Date Tue, 06 Nov 2001 09:39:46 GMT
Hello!

We're developing a larg databasepowered site using a mixture of
jsp, taglibs and includes. Everything works just fine in jrun,
but in tomcat it's extremely slow:


These timings show the output of "time curl -s -o /dev/null 
site/page.jsp"
accessing precompiled JSPs.

Using Tomcat:

real    0m12.705s
user    0m0.000s
sys     0m0.020s


Using JRun:

real    0m0.053s
user    0m0.010s
sys     0m0.010s


I highly suspect Tomcats taglib-implementation in combination
with the include-directive causing the problem. With the
"right" combination of includes and tags I've seen Tomcat
stuck in an endless loop, consuming all memory and crash.

Unfortunately I can't provide much more information, since
this is a closed-source project, but I would appreciate
any hints on where I should try to find the source
of the problem.


Thanks

Jens Askengren
