Here's the current setup:
There are 5 CIFS shares presented from the 3x2TB RAIDZ volume - music, photos, etc. One of the shares currently has 910 subdirectories. If it has not been browsed to in a while, it will take several seconds before the contents are listed. I don't know if there is a tunable for this somewhere? Once the directory structure is 'loaded into memory' browsing performance is fine - and it will stay this way for some time, so closing and re-opening the share do not experience the delay.
Question 2:
After reading http://forums.freenas.org/threads/some-insights-into-slog-zil-with-zfs-on-freenas.13633/ this thread, I am lead to believe that my 'transaction group' size is probably too large for the 4 mirrored pairs - 1/8 of 48 = 6GB. Is this tunable as well?
Thanks.
- DL380 G6 48GB RAM
- Flashed IBM M1015, HP SAS Expander
- 4 mirrored pairs of 146GB 10K SAS presented as NFS to VMware, using a pair of Intel SSDs for SLOG
- 3 2TB drives in RAIDZ for storage volume
- zfs.arc_max tuned to 32GB, ARC size sits around 26GB
