Hello!
Here are some new 2.2.2 pre2 test result: If you don't remember, here is a short description of the test.
I made heavy load with the kernel-compiling (make -j), and paralelly, I started 7 other tasks like this: ------------ #!/bin/sh while /bin/true do /bin/echo -n "#" sleep $1 done ------------ The parameter was 1 2 4 8 16 32 64 These programs echoes one symbol after every x seconds. These are redirected to different files, and counted after finishing the kernel-compilation has finished. The reading of the test results: First line: Kernel image name, user space, kernel space time, and CPU% (like time), and the total compilation time in seconds. Second line: The (number of #s per second * 10000 * program parameter ) in the shell script outputs. If this number is lower, it menas that the program had less time to put the # sign. In normal case, every test result should be around 10000, because, the shell script speed is 1/parameter hashmarks/sec. ac means Alan Cox patch, ar means Andrea Arcangeli patch.
results:
