Wipes egg from face. /etc/sysctl.conf: vfs.hirunningspace=4194304 So, then did r251446 actually start using this value or did other values get significantly tuned up? I recall now setting this nearly a year ago when we did our ZFS tuning and it was a four fold increase on the defaults. Sorry for the noise.
