We have an environment with a fuse (2.9.2) file system (high level api) on
Centos 6.3 (2.6.32-279 kernel) and a number of network based applications
writing to it. Using NFS, we are getting very good write performance with
fuse. However with SMB via samba (3.6.10), we are experiencing significant
performance degradation (slightly below half the write throughput) with fuse
when compared to either NFS performance with fuse or samba writing directly
to ext4 (underlying file system).
We've been investigating options to improve performance and it appears that
the fallocate support is the best lead, however we're stuck with the 2.6.32
kernel in this environment (patching may be an option, but certainly not
preferred). Are there other possibilities that we should consider to
improve the performance when using fuse in conjunction with samba?
