Squid does not care about partitions. Two partitions on one drive spindle with a cache_dir each will have as may IO clashes as two cache_dir on one partition on the same drive spindle. > Does having multiple directory have any effect or there should be only > one directory per drive ? Per Spindle. Partitions only matter if your drive is advanced enough to have multiple independent read/write heads and your partitioning is fine grained enough to match exactly to a particular platter. The disk rule-of-thumb generalization is one physical disk one cache_dir. The exception being COSS which can be paired with another cache_dir type on one drive. Amos
