Basically, it measures linux kernel's compiling time. The kernbench script can be downloaded at the following web site. http://freshmeat.net/projects/kernbench/ lat_ctx is a performance analysis tool in LMbench. lat_ctx measures process context switching time. The overhead of the CPU controller is a difference between the context switching time of original 2.6.15 kernel and CPU controller enabled 2.6.15 kernel. LMbench tools can be downloaded at the following web site. http://www.bitmover.com/lmbench/ > I guess that you usually use kernbench to see CPU resource controller > working.

Of course, the simple way is also OK to see CPU controller working. The reason I uses kernbench is that it is more similar to real workload. > btw..what is vannila 2.6.15 ? Sorry for my ignorance. Sorry for the misspelling. It was vanilla 2.6.15, which means original/pure 2.6.15 kernel.
