Hi,
I am having some performance problem on my MPC850 board. When i setup a very
small main that only executes like 100 asm instruction then it takes around
6-7 times the teoretically time. My first thought was that the caches wasnt
turned on but when i turned them off - before my short loop - as a test,
then i got a further decrease of performance (3.5 times).
Does anybody have any ideas of what maight be wrong here?
