| Woofybean | bit of a left field question, reviewing various bits of performance tuning, any modern up to date pointers for tuning directory cache and so on for fast rsync and content listing? | 02:48 |
|---|---|---|
| sarnold | Woofybean: the bytes in here are kinda specific to my machine -- 128 gigs ram, and I wanted the filesystem to 'own' the machine: $ cat /etc/modprobe.d/zfs.conf | 02:53 |
| sarnold | options zfs l2arc_write_boost=1073741824 l2arc_write_max=1073741824 zfs_arc_max=120847181648 zfs_arc_meta_limit_percent=95 zfs_arc_dnode_limit_percent=75 | 02:53 |
| sarnold | that raises the arc from 64g to 120g, drastically raises the meta limit to 95 of arc, drastically raises the dnode percentage of the meta portion to 75 percent of that | 02:53 |
| Woofybean | thanks sarnold, I'll give that a test | 03:05 |
| Woofybean | this is a 256GB machine, so more than sufficient for caching the directory tree | 03:05 |
| sarnold | hah I'll say | 03:06 |
| sarnold | mine was tuned to try to provide good ripgrep speeds over the unpacked archive | 03:06 |
| sarnold | the 'normal' archive might have fit in the defaults | 03:06 |
