SubjectKernel compile Performance Test
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.
