SubjectBOGOMips, CPU speed, compile times and cache
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 :)
