poor relative G4 performance iBook/PowerBook
Hi!
I develop on both an iBook G4 14" (should be one of the latest model,
although the motherboard ) and a PowerBook G4 17" both running debian...
Although currently different kernels, minor differences.
"In theory" I got the PB G4 because it should be faster than the iBook
* Same CPU version, but faster clock
* more RAM
further down "cpuinfo.
As a reference I use compiling ArcticFox which is a big, memory hungry
task: compiling, linking large files (unified sources!), copying stuff,
tar.gz, install... etcc
I know from working on x86 that 1.2GB are "tight" so in certain
situations. quite some swapping.
However, surprise surprise, build times on the iBook are around 6 hours,
on the PowerBook around 9 !!! That's a huge difference.
Either the PB has some hardware inferiority (design or degradation) or
there is something heavily under-performing on it - kernel issue?
setting? speed?
Ideas welcome :)
Some specific benchmarks easy to run and available in packages? eg.g.
memory speed and disk speed tests.
