Hello parisc-linux hackers,
Here are the LM Bench Mark results I recently ran on my C200+. The
HP-UX 10.20 bits are a couple of years old and not current on patches.
The 2.4.18-pa11 box is running debian unstable and is current.
Neither OS was tuned for this bench mark, but but OS were run on the
same box with the Same hardware configuration.
Hopefully these results someone will find interesting.....
