Pawel Jakub Dawidek f5a2f7feac Implement new reading algorithm, which will use parity component for reading ... as well, even if device is in complete state. I observe 40% of speed-up with this option for random read operations, but slowdown for sequential reads. Basically, without this option reading from a RAID3 device built from 5 components (c0-c4) looks like this: Request no. Used components 1 c0+c1+c2+c3 2 c0+c1+c2+c3 3 c0+c1+c2+c3 With the new feature: Request no. Used components 1 c0+c1+c2+c3 2 (c1^c2^c3^c4)+c1+c2+c3 3 c0+(c0^c2^c3^c4)+c2+c3 4 c0+c1+(c0^c1^c3^c4)+c3 5 c0+c1+c2+(c0^c1^c2^c4) 6 c0+c1+c2+c3 [...]		2004-08-21 18:11:46 +00:00
