From 80cb838773f3574f68b1fa821fcb712ada350309 Mon Sep 17 00:00:00 2001 From: Raghavendra Gowdappa Date: Tue, 12 Feb 2019 18:33:44 +0530 Subject: read-ahead/io-cache: turn off by default We've found perf xlators io-cache and read-ahead not adding any performance improvement. At best read-ahead is redundant due to kernel read-ahead and at worst io-cache is degrading the performance for workloads that doesn't involve re-read. Given that VFS already have both these functionalities, this patch makes these two translators turned off by default for native fuse mounts. For non-native fuse mounts like gfapi (NFS-ganesha/samba) we can have these xlators on by having custom profiles.
