Squid Mem + HugeTLB

Hi,

I was thinking if it made sense to use HugeTLB for the squid memory/buffer
subsystem and was about to hack it in.

I don't know how big other people run their memory caches, but mine is sized
around 256MB - which makes it > 65000 pagetable entries (at 4kb/page) which
absolutely kills any TLB or caches when walking the tables on a miss
(locality issues aside). It further is a stressing factor on the VM subsystem.

With HugeTLB (normally has 4MB pages) there would be only 66 which fits most
TLBs entirely.

What do you developers think - worthy addition?

Kind regards,
Ronny
