Dear All,
I just started working for a company named A3Cube, who produces HPC
supercomputers.
I was assigned the task to investigate which improvements to gluster are
viable
in order to lead to overall better performance in latency and throughput.
I'm quite new to SDS and so pardon me if some questions are naive.
From what I've understood so far, possible bottlenecks are
in FUSE and transport.
Generally speaking, if you have time to just drop me some pointers,
1] FUSE + splice has never been considered (issue closed without real
discussions)
(probably because it conflicts with the general architecture and in
particular
with the write-behind translator)
Recently, it has been announced a new userspace fs kernel module, ZUFS,
whose aim
is to zero copy and improving vastly over FUSE: would you be interested
in investigating it ?
(ZUFS: https://github.com/NetApp/zufs-zuf ;
https://lwn.net/Articles/756625/)
2] Transport over RDMA (Infiniband) has been recently dropped:
may I ask you what considerations have been made ?
3] I would love to hear what you consider real bottlenecks in gluster
right now regarding latency and thruput.
Thanks in advance
Kind regards
Federico
