What would be considered a large disk cache?
If I have a cache of 100Gb, would it be considered a large disk cache?

Yes, to squid anything over 20GB is 'large', though 'huge' is in the TB ranges.

The default garbage collection boundaries are very heavy-handed and may cause periodic slowness while tens or hundreds of MB in small KB files are erased.


Is there a number (approximatively) of a ideal size per HD (SAS 10000 RPM)?

Squid can handle up to 63 cache_dir. Each one ideally on exactly one unique HDD / 'spindle'. IIRC Henrik last spoke of 3 HDD being optimum for access vs data retention. With minimal gains going to more. I'm not sure if thats changed.

A cache of 100Gb (autofs) would reside in 1, 2 or 3 HD? or more?

Thanks
Ronan
