Achieving high performance squid

I've implement some of multi mixing storage type in squid.

COSS recently, as squid 2.6 stable inclusion became much more stable, I tried to implement it as other storage complementing the now used storage type AUFS.

First, I tried to implement it as one big cache partition file (3GB). As I monitoring for couple of days, I decide to implement it as real raw partition data (10GB).

I put COSS first in configuration sequence, and then followed by AUFS.

COSS partition used to hold the small object size, AUFS hold larger object size, all is controlled in automatically by squid cache store mechanism.

The result:

  • lower I/O bottleneck
  • much higher transfer from the cache box to the client
  • can serve client without waiting delay time (noticeable)

Improvement over last configuration that I've implement.

nice! :D
