There where some talk here a few weeks back about the usefullness of the BOGOMips number. A lot of people seemed to think that compile times was a better way to messure CPU preformance (at least when RAM was not an issue).
I decided to add another 128KBytes cache yesterday, and thought I'd see how that influenced compile times. Here if what I found:
In both cases I booted the computer, cd to /usr/src/linux/, make mrproper, make menuconfig, loaded a saved config, make dep, make clean, and then ran:
time make zImage
The results where:
128KBytes cache:
User: 1634.55 System: 87.53 Elapsed: 29:17.45
256KBytes cache:
User: 1091.30 System: 82.78 Elapsed: 20:08.36
Just wanted to add my 2 cents.
Flames via eMail, followups to the list :)
