Improving NS & IIS Response in Large Environments

There is a KB article available for "Common problems for very large environments" and is #26878. Particularly interesting is the last item under NS relating to IIS and .NET's debug mode for asp pages.

Quite a few solutions that are out right now that mistakenly have Debug enabled. This causes additional load on IIS / NS server.

Turning the debugging off on the asp.net pages should help in these three areas according to the KB article.

1. The compilation of ASP.NET pages takes longer (since some batch optimizations are disabled)
   This can be seen in the initial viewing of each NS console page
2. Code can execute slower (since some additional debug paths are enabled)
3. Much more memory is used within the application at runtime
   This is of particular importance on NS servers with 2GB of physical memory, and large client facing servers with multiple Altiris solutions enabled

Please see KB #33499 for more information and also to get the executable that will turn off debug mode on the .NET pages.

I also found that when I implemented it, it "hung" all Web pages for 2-3 minutes. Probably, while they recompiles. I'd recommend do this during off-peak hours. I did get great performance gains though.
