Linux 2.4 und 2.6 vs. FreeBSD/OpenBSD/NetBSD
Verfasst: 19.10.2003 21:08:30
Felix von Leitner aka Fefe ließ die verschiedenen BSD-Varianten (in der jeweils aktuellen Version) und GNU/Linux (mit aktuellen stable-Kernel 2.4.22 und mit 2.6.0-test7 Kernel) in verschiedenen Dizplinen auf gleicher Hardware gegeneiander antreten:
Ergebnis:
Platz 1: Linux 2.6
Platz 2: FreeBSD 5.1
mit Abstand:
Platz 3: Linux 2.4
dicht gefolgt von Platz 4: NetBSD 1.6.1
abgeschlagen:
Platz 5: OpenBSD 3.4
In Fefes Worten:
"Conclusion
Linux 2.6 scales O(1) in all benchmarks. Words fail me on how impressive
this is. If you are using Linux 2.4 right now, switch to Linux 2.6 now!
FreeBSD 5.1 has very impressive performance and scalability. I foolishly
assumed all BSDs to play in the same league performance-wise, because
they all share a lot of code and can incorporate each other's code
freely. I was wrong. FreeBSD has by far the best performance of the
BSDs and it comes close to Linux 2.6. If you run another BSD on x86,
you should switch to FreeBSD!
Linux 2.4 is not too bad, but it scales badly for mmap and fork.
NetBSD 1.6.1 was treated unfairly by me because I only tested the stable
version, not the unstable source tree. I originally only wanted to
benchmark stable versions, but deviated with OpenBSD and then with
FreeBSD. I should have upgraded NetBSD then, too. Nonetheless, NetBSD
feels snappy, performs well overall, although it needs work in the
scalability department, judging from the old version I was using.
Please note that NetBSD was the only BSD that never crashed or panicked
on me, so it gets favourable treatment for that.
OpenBSD 3.4 was a real stinker in these tests. The installation routine
sucks, the disk performance sucks, the kernel was unstable, and in the
network scalability department it was even outperformed by it's father,
NetBSD. OpenBSD also gets points deducted for the sabotage they did to
their IPv6 stack. If you are using OpenBSD, you should move away now."
Ich finde das ganze nicht unineteressant. Insbesondere, dass Linux 2.6 anscheinend so schnell ist, dass es sogar das überall als so performant gelobte FreeBSD übertrumpft, finde ich beeindruckend und erhöht meine Spannung auf den neuen Kernel.
Man muss fairerweise dazu sagen: Fefe ist Linuxfan.
