Subject: [dpdk-users] Hugepage size on x86 architectures:
Date: Sun, 6 Aug 2017 13:31:48 +0300	[thread overview]
Message-ID: <CAGXs5wWpb8HS6Yin2VBuBBQtDF+xs4k9H6iLxyJxo-d7gkc5Sg@mail.gmail.com> (raw)

Hi, dpdk users,

I read the section about hugepages in:
http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html?highlight=hugepages

So I understand that the common hugepage sizes used in x86 architectures are 2MB
and 1GB (if 1GB is supported on the CPU, which can be checked by
inspecting the CPU flags).

Is it possible to use in DPDK other hugepage size than 2MB and 1GB (in
order to benchmark performance)
on x86 architectures)?
In case it is possible - is it expected that different hugepage sizes
than 2MB and 1GB
will give less performant results ?

WK
