Hi,

This patch series make maximum read/write request size tunable in FUSE.
Currently, it is limited to FUSE_MAX_PAGES_PER_REQ which is equal
to 32 pages. It is required to change it in order to improve the
throughput since optimized value depends on various factors such
as type and version of local filesystems used and HW specs, etc.

This truly is a joyful week for FUSE :-).

Are these patches compatible with the fuse write-back patch series
posted by Pavel a few days ago?


I applied this patch series to the latest upstream kernel and measured
the read/write throughput using it. So, I have not try Pavel's patch yet.

However, I think it is compatible with his write-back patch series
since it just makes maximum limit of fuse request size tunable.
And my patch will be effective even for direct I/O.

Thanks,



Thanks,

-Nikolaus
