The article in the German magazine c't (lower case, please) was mentioned
in Lars Wirzenius's LinuxNews #3. The article also has a benchmark (the
"Byte Unix Benchmarks", if that rings a bell), as follows (the bigger
the numbers, the better):

machine/MHz             486/33            Sparc2/40       Sparc ELC/33

Oh yes, and Bill Gates was here last week.

                           This is probably a testimony to the
copy-on-write technique of memory mgmt.  SunLOSS *still* doesn't use it,
according to one of the original BSD developers due to a bug in the VAX-750
MMU it was never incorporated in BSD, and of course Sun would never lower
themselves to *do it themselves*...

All in all, an impressive testimony to a small, hand-optimized kernel
for very common and cheap hardware...
