Nathan,
aio with directio is still work in progress which can be tracked here
http://git.gluster.com/?p=users/csaba
/linux-fusehacks/.git;a=shortlog;h=refs/heads/topic.directio1
This needs to be fixed in the fuse kernel module itself. I think this
is what you were
looking at perhaps.
Well disable-direct-io can be done away as since 2.6.26 fuse kernel
module supports
big_writes which even with disabling direct io you get good performance.
Regards
