Is the CE operating Bench mark test, OSBench.exe, available for the GMaster?
(OSBench is used to measure the time required for the kernel t perform operations such as thread swithcing and event synchronization. - this info was found on msdn.microsoft.com website.)
Microsoft provided the source for OSBench.exe for CE .NET (so 4.0 and up). I've compiled it for the ARMv4 and ARMv4I and posted the binaries at Topic 1283. I've not tried running it under 3.0, but after a cursory glance at the source I think it should work.
