@Perf-team,
Do you think the gains are significant enough, so that smb and nfs-ganesha team can start thinking about consuming this change?
regards,
Raghavendra
This is a large gain but I think that we might see even larger gains (a lot
depends on how we implement copy offload :)).
Worth looking at how we can make use of it.
thanks!
Ric

Subject: libgfapi zero copy write - application in samba, nfs-ganesha
Hi,
I have carried out "basic" performance measurement with zero copy write APIs.
Throughput of zero copy write is 57 MB/sec vs default write 43 MB/sec.
( I have modified Ben England's gfapi_perf_test.c for this. Attached the same
for reference )
We would like to hear how samba/ nfs-ganesha who are libgfapi users can make
use of this.
Please provide your comments. Refer attached results.
Zero copy in write patch: http://review.gluster.org/#/c/14784/
Thanks,
Saravana
