Hi,

We think of using Linux HugePages to isolate shared memory used by Postgres, hoping that
we got more performance.
I see some souce code samples for doing that, but I do not see any information
about compatibility : Postgres 7.x, 8.x, 9.x
about recommandations
Thanks by advance.
Didier Sterbecq.

if you are using a kernel older than 2.6.38, you can use this with LD_PRELOAD:

With 2.6.38 and up, HugePages are used automatically in giant allocations.
