> I tried to tweek the value of loops_per_jiffy manually (just for testing, i have no intensions of replacing calibration function :)) on my ARM11. For example setting loops_per_jiffiy value such tthat i get 140 BogoMips, the throughput incereased considerably to 66Mbps, but CPU usage remained around 85%. And using diffrent hard coded values of loops_per_jiffy i got diffrenent Throughput values and CPU usages. loops_per_jiffy is used in udelay() and mdelay() functions, which are delay loops for a certain amount of micro/miliseconds. What you did is artificially override drivers that wanted to delay a certain time to delay shorter. This is usually a very bad idea; those delay loops are there for a reason (although some device drivers are just plain stupid and abuse them a lot... which network driver did you use?) -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org -- Kernelnewbies: Help each other learn about the Linux kernel.
