Achieving higher performance?

Hello i want to make my design as fast as possible to run uCLinux, my software is running at 40ms and should run at 8ms. I am using a linux with MMU, 50mhz clock, 32k Data and instruction Cache...

I've tried -O3 and -O2 flags and the result isn't really good also (these flags are only at my application Makefile)

Well to be honest the only thing that did make a difference was changing the data/instruction cache from 32 to 64k..

I really think i am not doing something correctly when compiling my linux image
