[Gluster-devel] AFR write speed, ouch!

[Brandon Lamb]

I did see a post awhile back about the new AFR killing write speeds,
any update on this?

I setup a 2 server (both are server/client) and only mounted the afr
brick on one of them and attempted to untar linux-source-2.6.26.tar...
what took 5-9 seconds on the local disk took over 5 minutes on the afr
mount.

Are there any tricks I can employ? Is there an option to use such as
"i dont care about autonomous locks" or something? Hm I havent tried
WITHOUT afr, i'll go try that, but this seems kind of odd.
