Hi everybody,
this is my system:
FreeNAS-8.3.0-RELEASE-p1-x64 (r12825)
Supermicro X7SBE motherboard
Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz
8GB RAM
Intel PWLA8494MT PRO/1000 MT Quad Port Server Adapter with link aggregation
L2 managed switch that support link aggregation
Separate network for NAS
4x2TB Seagate Barracuda RAID 0
----
Read performance:
dd if=/mnt/RAID/tmp.000 of=/dev/null bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 185.820114 secs (577839395 bytes/sec)
----
Goal is to provide consistent read speed for 3 AFP clients, ideally about 110 MB/s per client. Before Freenas I was testing Debian + XFS + Netatalk, and I was getting those results w/o any tweaks.
However I really like ZFS & Freenas (it just saved me from bad RAM and serious corruption), and I want this to work with Freenas.
With single client performance is fine - about 110 MB/s Read & Write, although a bit "bumpy" (it goes to 113 than down to 103 ...). However, when I start simultaneous test from second client, write speed stays where it was while read speed drops to 50-60 MB/s.
I have tried to find the solution, but without success. Am I missing some Tunables / Sysctls?
Thank you in advance.
