Test 1: time to boot the kernel, from hitting enter at the LILO
prompt to getting a login prompt
Test 2: time to "rm -rf" a clean linux-2.4.17 source tree, using
the newly booted kernel (no other access to the tree before that,
so it wasn't cached in any way, and the machine was otherwise idle)
Test 1 Test 2
2.2.21pre2: 71 sec 75 sec
2.4.18pre1: 64 sec 72 sec
2.5.2-pre7: 97 sec 251 sec
I haven't noticed any slowdowns on my other boxes, so I didn't
do any measurements on them. On the 486 it's very very obvious.
