Gents, Under 4.3 and the associated kernel it took 17 seconds to recompile my entire application on my amd 4800+ X2. Down from 1 minute and 20 seconds on my old platform. I just tried under the new 2.6.9-42 kernel and it is 15 seconds. So that modification to the kernel for disk improvement seemed to help my compile time... Just sharing... Great work on 4.4. Jerry
