https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224080 --- 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. Tho= ugh ARC is more in line with as it was before r326347, MFU fluctuates widely, f= rom 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 22:0= 7:05 123 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 CO= MMAN 2503 root 1 24 0 58704K 35612K select 1 2:16 7.25% Xo= rg 2658 cy 5 22 0 93644K 46620K CPU0 0 2:16 6.99% ma= te-t 50487 root 1 4 10 10476K 1836K select 2 0:00 1.53% ma= ke 49701 root 1 52 10 17436K 9024K select 1 0:00 0.16% ma= ke 2591 cy 1 20 0 16804K 6684K select 2 0:02 0.08% xs= cree 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% ma= ke 48259 root 1 30 10 10956K 2336K select 2 0:00 0.06% ma= ke 46730 root 1 30 10 11036K 2344K select 1 0:00 0.06% ma= ke 3041 cy 1 20 0 12708K 3704K select 0 0:01 0.05% kr= logi 25290 root 1 30 10 11128K 2416K select 2 0:00 0.05% ma= ke 49044 root 1 20 0 11040K 2656K select 0 0:00 0.04% mo= used --=20 You are receiving this mail because: You are the assignee for the bug.=
