Subject: [RFC] [PATCH 0/2] OrangeFS in-kernel lookup and attribute cache
Date: Tue, 5 Jul 2016 15:13:47 -0400 [thread overview]
Message-ID: <1467746029-4199-1-git-send-email-mkb@localhost.localdomain> (raw)
This patch introduces caching for OrangeFS server lookups and getattrs.
The userspace OrangeFS client has done this in the past. We see a
significant (3 to 4 times) performance improvement with these patches
at a cost of consistency across the cluster, which OrangeFS doesn't
really guarantee anyway.
Martin Brandenburg (2):
orangefs: Use d_time to avoid excessive lookups
orangefs: Cache getattr results.
