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
os Linux 0.97 SunOS 4.1.2 SunOS 4.1.1
Arithmetic 1.1 3.1 2.0
Dhrystone 1.2 1.6 1.3
Execl Throughput 7.1 1.2 1.5
File Copy (30sec) 2.3 1.5 1.6
Pipe-based Context Swtch 3.3 1.5 1.4
Shell Scripts (8 conc) 2.5 1.4 1.2
sum 17.5 10.3 9.0
mean 2.9 1.7 1.5
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...
