[MooseFS-Users] Two mounts or one? what has better performance

[WK <wk...@bn...>]

We have a project where we have a machine that is talking to a MFS3 
cluster for two purposes

The main purpose is a very busy file repo, we are also copying off large 
archives in to a backup folder 2-3 times a day.

We want to reduce latency on the files as the client is somewhat picky 
and want to avoid the archive dump slowing things down.

What is the best way to handle that

A) one mfsmount to /mfs3mnt

with subdirectory /mfs3mnt/backup  & /mfs3mnt/files


b) Two seperate mfsmounts on the client

/mfs3backup

and

/mfs3files

Security isolation is not a concern.

So what would provide the best performance? or does it really matter?

The connection would be 1GB ethernet with jumbo frames.


Note we are considering that with two mounts we could use seperate 
ethernet cards, however its not an option immediately as the host has 
used up all the ports with other needs.

If you feel strongly that would make a difference then I can push a host 
migration on the client.

And of course 10G is getting reasonable, but still not a default on our 
somewhat older kit.
