The bigger blocksize the faster I presume..
Yes that's the rule - as far as I know, any multiple of 512 is fine, but the optimal blocksize will depend on the hardware. I often use 65536.
Traditionally there were two limits to optimise the transfer: (1) make sure that the blocksize*block count will fit in real memory! (2) typically, use a multiple of the disk's track size (depending on the exact actuator mechanism and/or sector skew)
I've no idea how those criteria translate with current disks.
Same here. I think there are too many variables to work it out, so it's trial and error. /Per -- Per Jessen, Zürich (6.8°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
