Hi all (cc maintainers),

We've tried a performance test comparing nfs-ganesha and gNFS from gluster, we 
found that gNFS out performs nfs-ganesha by nearly 2 times on OPS.

As I read throught the code FSAL_GLUSTER now adopts sync api from libgfapi, is 
there any plan to switch to the *_async ones, so we could possibly gain a 
performance boost ?



Which protocol have u tried and which version of ganesha/gluster packages?



Also, my proposed Ganesha V2.6 code has a more async input.  Even UDP
should be much faster, as the original TI-RPC code (and previous nTIRPC)
handles them one-at-a-time (using 1 buffer), whereas my code allows many
in parallel.

You'll find that in
  https://review.gerrithub.io/#/c/369641/

or
  https://github.com/linuxbox2/nfs-ganesha/tree/was26napalm

Besides, I'd appreciate any bug reports

Hi Mark,

As a matter of fact that is one of a bunch of perf and async/non-blocking
changes being worked on for 2.6 and later releases.

Soumya is the person currently working on gfapi async.

[Nfs-ganesha-devel] About FSAL_GLUSTER performance

[gui mark]

Hi all (cc maintainers),

We've tried a performance test comparing nfs-ganesha and gNFS from gluster,
we found that gNFS out performs nfs-ganesha by nearly 2 times on OPS.

As I read throught the code FSAL_GLUSTER now adopts sync api from libgfapi,
is there any plan to switch to the *_async ones, so we could possibly gain
a performance boost ?

Thanks,
