NetBSD 2.0 vs FreeBSD 5.3

Gregory McGarry has made a benchmark comparison between NetBSD 2.0 and FreeBSD 5.3.
(via mindtrap::weblog)

The main differences are that NetBSD scales O(1) on forking new processes while FreeBSD scales O(n). For memory mapping and socket creation both scale O(1) but NetBSD is twice as fast as FreeBSD
But for binding addresses to sockets, FreeBSD scales O(1) while NetBSD scales O(n) but is twice as fast for a small number of bound sockets. Also for POSIX thread creation FreeBSD scales O(1) while NetBSD scales something like O(n) and is twice as fast for a small number of threads.

This paper has presented a suite of benchmarks and results for comparing the performance of NetBSD 2.0 and FreeBSD 5.3 in the areas of core operating system functionality, network scalability and thread performance.

The results clearly indicate that recent architectural decisions in the NetBSD operating system have closed the performance gap between NetBSD and FreeBSD. In fact, NetBSD has surpassed FreeBSD in performance in the areas investigated in this paper. Significant performance improvements are obviously visible in the thread implementation.

NetBSD

Hier wird versucht Mac OS X Anwendungen unter NetBSD zum laufen zu bringen.

Da ich auf meinem PowerBook gerne einige kommerzielle Programme benutzen möchte, aber dennoch auf die Programmvielfalt eines "freien" Unixsystems nicht verzichten möchte, habe ich vor mich in Zukunft etwas mit NetBSD zu beschäftigen.

Der erste Schritt dazu ist schon gemacht: Seit gestern Abend läuft auf meinem alten Testrechner NetBSD 1.6.2 :-)
