Recompiling the kernel and customizing it (i.e. leaving things out that you don't need) are not very hard at all. Things like enabling kernel thread preemption and file system softupdates might help with performance. But in general you could say that removing code for devices and subsystems that aren't used anyway might speed up booting a bit, but will not help much with speeding up daily usage. The tuning(7) manpage gives lots of tips on getting the best performance out of your system. Note that the kernel occupies only a small section of the material in that page.=20 For instance, for a file server the file system layout is much moe important due to higher transfer speeds from the outer edges of the disks.
