We've got a .NET application as a front end with a Java based ECM solution as a backend. So the front-end does requests to the back-end through IIS. The issue is that it works fine for GET requests, but POST requets are most of the times really slow (not always). We've tried doing POST requests using the POSTER plugin for firefox and i...

Ive created a program that needs to commit to repositories. I'm using slikSvn. It seems that the very first commit I make is very slow (20 sec) but every other commit is much faster more like 1 sec.
