Yes. > Will multiple cache dir increase the performance? You should use one cache_dir per disk for best performance is using aufs. With diskd sometimes performance can be increased by having more than one cache_dir for the same disk, but the difference is marginal and I'd recommend a single cache_dir per disk for diskd also. > Each disk is 36 GB, so is it a good idea to increase the "Level-1" > and "Level-2" numbers? 6 * 36 GB = 216 GB 216 GB * 10MB / GB = 2.16 GB of memory required. do you have this amount of memory available, and can your platform support this big processes? But to answer your question L2 = 256 L1 = size / 500 or bigger (rounded upwards) The main criteria is that L1 is not too small and L2 not too big for the filesystem. Having L1 too big will only waste some disk space. No impact on performance either way. Having L1 too small or L2 too big will waste a little CPU time Having L2 too small will waste a little memory for disk structure cache. The differences are not large, but the recommended sizes above works well.
