Thank you amos  for explanation ,
You also didn’t answer me , does that mean in 3.5 squid version the object size in rock store  can be like 500KB ? or 1M ?
Or there is still has limitation for max size ? I know it exceed the 32kB , does that mean it can save like 1 M object size ?
==================

The 1nd question , I have 3.head squid version Its Squid Cache: Version 3.HEAD-20141105-r13687


Will I find a big performance in rock   in comparison to 3.5 ?

Does that version im using right now has limitation on rock ?

cheers

What "it" ?

SMP memory is the only one restricted to 32KB. Because 32KB is the default UDS (Unix Data Socket) packet size limit, and Squid SMP code is assuming that limit is in place even if the sysadmin has altered the kernel to accept larger packets.

Squid-3.5 has 5 cache areas in which HTTP objects can be stored:

* Transients Memory (in-transit objects cache)
* SMP shared memory cache (cache_mem between workers)
* Local memory cache (cache_mem for local worker only)
* Rock disk cache
* UFS disk cache (ufs, aufs, diskd)

Only two of those have *ever* been limited to 32KB (Rock and SMP shared memory), and in 3.5 that is reduced to one (shared memory cache).

The others are not limited by object size, but by total cache space.
