Yes I know
I'm using lots of custom written tools mainly CMD tools, small EXE's, so that's reason I have to stay Windows all the way.
Or installing VMWare Workstation on CentOS - running optimized Win 2003 for CMD tasks, and Hiawatha under Cent.
Hiawatha - small memory footprint/features compared to monster Apache and it's horrible memory leaks over time.
I will run some heavy benchmarks in few days.
