[fuse-devel] write size stuck at 32k?

[JT O. <jt...@xn...>]

Hey everyone,

 First off, this is one of the most helpful mailing lists I've been on
recently, so I just wanted to say thanks to all of you.

A quick question about write sizes: I'm on Linux 3.2.0 with FUSE
2.8.6, using the low-level API. I am using FUSE_USE_VERSION 26. I've
tried every possible combination of enabling direct_io when a file is
opened, and providing big_writes as a mount option. No matter what I
do, write requests clock in at 32K every time. I've actually gotten
performance to a pretty good place, but I'm a little confused why I
can't seem to tweak this value.

What might I be doing wrong? I also have max_read and max_write set at 128K.
