Bascially everything in section 2.2.3 (/etc/sysctl.conf) is wrong; some values may need tweaking, but changing them blindly will not be helpful. The one setting that I do suggest you keep is:
kern.ipc.somaxconn=512 (128 may be too low for http testing) The settings from section 2.2.4 will _probably_ be ok, but you'll have to run netstat -m after a benchmarking run to really know. One setting which you'll need to change for the apache2 run is kern.ipc.nsfbufs. Unfortunately, -stable doesn't have any way to tell if you're running out, so you'll have to just guess there. Under -current, netstat -m will tell you what you need to know. Also, you'll probably want to increase KVA_PAGES from 256 to 512 so that the kernel does not run out of memory. Under section 2.2.7, take out the section talking about CPU_FASTER_5X86_FPU through CPU_UPGRADE_HW_CACHE - none of these options is going to help, and it will just increase the likelyhood that something goes wrong. In general, it appears that you can run most of the benchmarks locally, so I suggest that you do that when trying to decide how to tweak settings. For the threads-related benchmarks (volcanomark and apache2 with worker) start asking for help on the -threads mailing list. This is the one thing that is likely to benefit from tweaking.
