Hi all,

the last days I have run the lmbench benchmark suite with cygwin and Suse Linux 7.1 on a Toshiba Satellite Pro 4300
Serie with PIII 700 MHz, 320 MB RAM.

I was very surprised about the differences in some tests. While some tests produces expected results for example in
the "processor results" there are other tests, about I'm wondering if this is true, like the context
switching, *Local* Communication latencies and *Local* Communication bandwidths.

Because of this, I don't like to comment the results, but I'm asking if anybody else could confirm this results.

BTW: But if this is true, I know why kde2 runs so slowly :-)

Regards
Ralf
