From b83b8efcf0673233bd28cddac4d62a639784a5c0 Mon Sep 17 00:00:00 2001 From: Krutika Dhananjay Date: Wed, 19 Sep 2018 15:49:27 +0530 Subject: [PATCH 375/385] extras: Add new options to group "virt" > Upstream: https://review.gluster.org/21222 > BUG: 1630798 > Change-Id: I231db309de0e37c79cd44f5666da4cd776fefa04 In some of the recent performance tests on gluster-as-vm-image-store use-case, it has been observed that sometimes the lone fuse thread can hit near-100% CPU utilization and become a performance bottleneck. Enabling client-io-threads (in addition to bumping up epoll threads on server and client side) has shown to be helpful in getting around this bottleneck and pushing more IOPs.
