Why do these stats differ from the ones in the zfs-stats script?
CPU: 0.1% user, 0.0% nice, 0.3% system, 0.1% interrupt, 99.5% idle
Mem: 81M Active, 1118M Inact, 9714M Wired, 76K Cache, 1850M Buf, 6930M Free
ARC: 6026M Total, 128K MRU, 1222K MFU, 24K Anon, 9961K Header, 238K Other
Swap: 18G Total, 18G Free
zfs-stats output:
ARC Size Breakdown:
Recently Used Cache Size: 0.67% 40.11 MiB
Frequently Used Cache Size: 99.33% 5.85 GiB
Shouldn't your MFU be 5.85GiB and MRU be 40MiB?
