Hi all!
I have a question regarding reads of a NFS mapped networked drive from an FreeNAS system, see signature, towards my MacBook Air.
When zfs sync is set to standard the browsing of a directory take "ages", seconds... (dir with a couple of 100 files in it).
When zfs sync is set to disabled the browsing of the same directory or other directory is lightning fast.
On the same wireless network, I have not moved the MBA.
Why is that? I thought that sync was only for writes? I know that ESXI and NFS is a performance hit when it comes to writes. But reads? When I´m seeing this behaviour I´m thinking of buying two small SSDs and using them in mirror as SLOG. But that will only help with writes.. or have I totally missed something?
I mount my NFS on the MBA using this command:
mount -t nfs -o soft,intr,rsize=8192,wsize=8192,timeo=900,retrans=3,proto=tcp 192.168.0.110:/mnt/tank /Volumes/tank
