AW: 2.4.26 and MPC885 context switching time

Hi Peter,

i'm evaluating IPC on the MPC885ADS and discovered
that the context switching times seem to be quite
disappointing (up to 1ms). As we need to do a lot

..=20

Or is this the expected context switching time for
CPU @ 100 MHz (RAM @ 50 MHz)? Suggestions for a
benchmark program?

Denx has done some detailed performance measurements=20
(including context switching). You could find the report=20
here: http://www.denx.de/twiki/bin/view/Know/Linux24vs26.
Hope that is of some help.
