I’ve been benchmarking EXT3 and ReiserFS on RAID 5 and RAID 10 (1+0). You can see my results so far online.
I’ve also been fiddling a bit more with OpenGL, but the vector maths are slowing me down at the moment.
I also bought an Xbox, which has slowed me down even further. It’s now chipped though so I’ll be fiddling with Linux on it. I love things with ethernet ports.
