Tux Machines (TM)-specific
With Linux Kernel 2.6.32 around the corners I see some guru's suggesting users to recompile their own kernels for a dozen of reasons: performance, fast booting, support of some esoteric drivers, bla... bla... What's more, the way some persuade for kernel recompilation seems the job is as easy as any point-n-click installation.
Dear users, kernel recompilation is not easy like that. Plus, you won't get that perceivable performance boost. May be after hours of toil you can cut down 2 secs from your boot time and some unnoticeable system responsiveness.
Except for some really weird situations, modern Linux distributions don't really need kernel recompilation.
