Ralf's article is really a nice source of information, how to build up webservers and how to tweak the FreeBSD kernel for better performance. This reminds me, that in articles with performance tests, FreeBSD doesn't always perform best as it could, because of numerous things we don't set in the GENERIC kernel. Couldn't we for example add another kernel profile based on GENERIC especially for larger scale internet server, which contains some more reasonable settings for better performance ? We should offer the user at the end of installation, which kernel to choose. We could install both, the kernel.GENERIC and kernel.INETSRV, but install the kernel the user chooses as /kernel. This only because not every tester is a Unix (BSD) guru .... Here are the diffs for a kernel with possibly better Inet Server Performance.
