OpenBSD optimalisation is rather about NOT touching the kernel - unless

you really have a specific need for it.

Run 'GENERIC'. That has worked remarkably well for my webservers for

years now.

If you are used to LAMP setups the only thing you might need to look at

is the MySQL configuration.

That might need it's own login class (busy servers) but I believe more

recent packages started mentioning this.

Otherwise search the archives or have a look at openbsdsupport [1]. Both

have the info on how to do it.
Assuming you are new(ish) to OpenBSD you might run into some other well

known pitfalls:
OBSD has the httpd chrooted [2] by default and php's mail capabilities

(which call /bin/sh) can therefor not work out of the box [3].

Also building by hand isn't needed / advisable - use packages [4]. If

that doesn't work check the ports [4] system

(which all should feel very familiar coming from Gentoo)
