From: wcheng@sourceware.org To: cluster-cvs@sources.redhat.com Subject: cluster/gfs-kernel/src/gfs super.c Date: Wed, 02 Aug 2006 01:29:00 -0000 [thread overview] Message-ID: <20060802012857.31409.qmail@sourceware.org> (raw) CVSROOT: /cvs/cluster Module name: cluster Branch: RHEL4 Changes by: wcheng@sourceware.org 2006-08-02 01:28:57 Modified files: gfs-kernel/src/gfs: super.c Log message: Bugzilla 199984: Increasing gt_statfs_slots tunable could significantly boost gfs "df" performance; e.g. set it to 128 from current default (64) could cut the "df" wall time in half with larger filesystem size. However, the kmalloc call within stat_gfs_async() has the possibility to fail due to increased gt_statfs_slots. There is really no need for this array to be on a piece of contiguous memory. Switch to vmalloc(). Patches: http://sourceware.org/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/gfs/super.c.diff?cvsroot=cluster&only_with_tag=RHEL4&r1=1.12.2.3&r2=1.12.2.4
