Hi Greg,
What hardware? What software versions?
The hardware I'm using is the Coldfire 5329 processor running at 240 MHz. It runs uClinux 2.6.16.1 from Freescale. It uses an NFS mount.
Are you using the same dhrystone code as was used to generate the vendors number?
Freescale also used Dhystone 2.1 in their benchmark test, but probably without any OS.
Is cache enabled?
I have browsed the Kernel configuration utility without finding the cache enable option. Where can I find it? Thanks for answering my questions. Regards, Sven

If a system has only one runnable process then it will get scheduled all CPU time. And normal kernel house keeping functions (like system timer) user a very small fraction of total CPU time. > -Does anyone know a way to give an application more CPU time? Is cache enabled?
