I built a monolithic kernel with all the modules statically built in, as I knew all modules I needed. Everything else, I did not need, I removed from the kernel. So I got a optimal kernel exactly for my machine. Then I took the booting time. After this I made a minimalistic kernel (nearly a microkernel) with only just the needed modules built in and left all other modules I needed as loadable modules. Then I took the booting time. At last I took the debian standard kernel and built it without any changes for my architecture. Then I took the booting time. What do you think? No, you are wrong, the difference among those three kernels in the booting time was not big, just maybe 1 to 3 seconds. However, building an own kernel might improve security, i.e. on my servers I removed the usbmodule and cdrom stuff, so that no one could easy connect evil hardware to the servers (we sometimes got visitors in the data processing center) Just my 2 cents...
