https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224080 --- Comment #13 from Cy Schubert <cy@FreeBSD.org> --- Looking at the workloads of my four systems, I'm not entirely convinced reverting r326346 will make as much difference as removing r326347 did. Though ARC is more in line with as it was before r326347, MFU fluctuates widely, from 55M to 500M. Better than single digit MB before. I will see if reverting r326346 makes a difference too. last pid: 50534; load averages: 1.32, 0.94, 0.96 up 0+01:05:30 22:07:05 123 processes: 2 running, 121 sleeping CPU: 1.6% user, 4.2% nice, 5.0% system, 0.6% interrupt, 88.7% idle Mem: 1018M Active, 1310M Inact, 3670M Wired, 178M Buf, 1763M Free ARC: 1327M Total, 177M MFU, 651M MRU, 15M Anon, 24M Header, 460M Other 283M Compressed, 943M Uncompressed, 3.33:1 Ratio Swap: 12G Total, 12G Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAN 2503 root 1 24 0 58704K 35612K select 1 2:16 7.25% Xorg 2658 cy 5 22 0 93644K 46620K CPU0 0 2:16 6.99% mate-t 50487 root 1 4 10 10476K 1836K select 2 0:00 1.53% make 49701 root 1 52 10 17436K 9024K select 1 0:00 0.16% make 2591 cy 1 20 0 16804K 6684K select 2 0:02 0.08% xscree 50489 root 1 52 10 11668K 3172K wait 3 0:00 0.08% sh 2560 cy 1 20 0 21684K 9336K select 0 0:03 0.07% mwm 23860 cy 1 20 0 14168K 4388K CPU3 3 0:01 0.07% top 50486 root 1 52 10 11688K 3176K wait 2 0:00 0.07% sh 25264 root 1 30 10 10224K 1388K select 1 0:00 0.07% make 48259 root 1 30 10 10956K 2336K select 2 0:00 0.06% make 46730 root 1 30 10 11036K 2344K select 1 0:00 0.06% make 3041 cy 1 20 0 12708K 3704K select 0 0:01 0.05% krlogi 25290 root 1 30 10 11128K 2416K select 2 0:00 0.05% make 49044 root 1 20 0 11040K 2656K select 0 0:00 0.04% moused -- You are receiving this mail because: You are the assignee for the bug.
