On Squid 2.5S13, using ufs/aufs, I am using the recommended 256 L2 cache directories. I find though that I never use more than about 140 of them. That is, roughly 115 of every 256 directories are untouched since the initial creation of the cache directory hierarchy. Is there any advantage (performance and/or memory utilization) to reducing the L2 dir count from 256 to, say, 150? Thanks.
