NiosIIuser,

I've had the same problem with 99% of the CPU time being gobbled up by the program. I had some minor success like Roger by recreating the project and then providing my own Makefile. Also, I found that if I've been working in the IDE for some time (5 to 7 hours) a restart of the board and entire machine seems to fix the problem for some time. It will also speed up the rate files are uploaded to the board. Since I'm using a USB Blaster, after many hours of uploading/resetting the CPU the uploads do take some more time to occur. Right now, that's the best 'solution' I can come up with. I hope this helps out.
