Thanks for the explanation folks.
So if I cannot get Apache/Webdav to write synchronously, (and it does
not look like I can), then is it possible to tune the ARC to be more
write-buffered heavy?
My biggest problem is with very quick spikes in writes periodically
throughout the day. If I were able to buffer these better, I would be in
pretty good shape. The machines are already (economically) maxed out on
ram at 32 gigs.
If I were to add in the SSD L2ARC devices for read caching, can I
configure the ARC to give up some of it's read caching for more write
buffering?
I think in most cases, the raw spindle throughput should be enough to
handle your load, or else you haven't sized your arrays properly.
Bursts of async writes of relatively large size should be headed to
the media at somewhere around 50-100MB/s/vdev I would think. How much
burst IO do you have?
