c't heeft eigen Linux vs WinNT webserver benchmarks gedraaid, waaruit blijkt dat de combinatie Linux / Apache opeens wél sneller is dan WinNT. Persoonlijk heb ik meer vertrouwen in c't dan in PC Week of Mindcraft. Hier heb je wat copy/paste uit de conclusie:
First of all, we must say that additional CPUs for plain web server operation with static HTML pages are a waste. Even with two Fast Ethernet lines there's only a moderate less than twenty percent increase. It seems that CPU performance is not the decisive factor with these tasks. The graphs indicate that the Primergy server itself didn't have to work to its full capacity at all.
Linux's comparatively bad results when tested with two network boards show that Mindcraft's results are quite realistic. NT and IIS are clearly superior to their free competitors if you stick to their rules.
To clarify it once again: These results correspond to a load beyond 1000 requests per second. In comparison: At peak times, the Heise server deals with about 100 requests/s. Also, we are talking about purely static pages which on top of that are already present in the system's main memory. Our tests showed that Mindcraft's result can't be transferred to situations with mainly dynamic contents - the common case in nearly every sophisticated web site.
In SMP mode, Linux still exhibited clear weaknesses. Kernel developers, too, admit freely that scaleability problems still exist in SMP mode if the major part of the load comes through in kernel mode. However, if user mode tasks are involved as well, as is the case with CGI scripts, Linux can benefit from additional processors, too. These SMP problems are currently the target of massive developing efforts.
In the web server areas most relevant for practical use, Linux and Apache are already ahead by at least one nose. If the pages don't come directly from the system's main memory, the situation is even reverted to favour Linux and Apache: Here, the OpenSource movement's prime products leave their commercial competitors from Redmond way behind.
