Please check out my latest book, Writing High-Performance .NET Code. p/s: Nice to meet you. 🙂 Remy March 7, 2010 at 3:50 pm Hi Ben, I wanted to use your program for my project, but the code uses GetSystemTimes() and GetTickCounts()

Manually browse to the folder and take a look at what's in there to get started. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. But even better is Environment.TickCount since it is not dependent on the user not touching their clock. * SubtractTimes can be static. * I rolled the two properties into the code, Glibtop The question does not have to be directly related to Linux and any language is fair game.
