Loadtester Incorporated have a wide collection of articles, whitepapers, PowerPoint's, Word Documents and PDF files all dealing with load testing, stress testing, and capacity planning.  You need not be unexperienced LoadRunner or Performance Tester to fully appreciate the articles.  Some of the resources that I find particularly useful are articles that cover counters for MS SQL 2000, Citrix, RDP Protocol Basics, WinSock Protocol and VTS. There are two links of resources to be precise, one to the articles written by the company.  The other to the library.  Click the below link to access the resources.
