Best .NET memory and performance profiler?

My C# program, a web scraper, makes extensive use of async HttpWebRequests, Regex, and HTML agility pack. It’s multi threaded using the ThreadPool.QueueUserWorkItem method.

It starts off using around 600,000 K of memory and eventually climbs to over 1,000,000 K.

How can I track what’s taking up the most memory and clean it up so it’s less resource intensive?

Thanks

Use a memory profiler – they can help to analyse such problems, for example:

• http://memprofiler.com/ (commercial, managed PLUS unmanaged integrated in one profiler!)
• http://www.red-gate.com/products/dotnet-development/ants-memory-profiler/ (commercial)
• CLR Profiler from MS (free)
