min: 1 flush/s max: 6 flush/s mean: 3.2 flush/s, standard deviation: 0.33 I have no idea wether this is high or low. > EF> How large are your stripes, btw.? > ED> It is the sectPerSU in raidctl -s output, right? > Multiplied by the number of data discs (i.e. discs minus one for level 5). This is a two-disk RAID 1 with this raidctl -s output sectPerSU: 32, SUsPerPU: 1, SUsPerRU: 1 Queue size: 100, blocksize: 512, numBlocks: 972799936 The answer would therefore be 32 * 2 =64 -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz [email protected]
