apache 2 module performance problem

[Jessica Wei]

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
