apache 2 module performance problem

[Jessica Wei <je...@witango.com>]

Hi, all

Our campany has an application server. We write an apache module to direct certain extension file requests to our application server. The module works fine funtionally. But recently we got some performance problem. The module works fine by itself but it causes other cgi stuff - perl and shell scripts - to run very very slowly. They take about
10 - 15 seconds to respond. If the Apache server didn't load our module, the other cgi stuff works perfectly.
It seems the module has some problem. But we really don't know what cause it. Could somebody give us any clue?

Thanks,

Jessica

Can you run an strace or trap it in the debugger and find out exactly
what's going on when it "pauses"?
