[Gluster-users] Glusterfs - Translators/Performance

[Rao, Uthra R. (GSFC-672.0)[ADNET SYSTEMS INC]]

Thank you Vijay for taking the time to reply.

What we want is writes to be a bit better than the 10MBps we are seeing but not as important as read which is good at 400MBps.  

Is it better to store settings in /etc/glusterfs/glusterd.vol (as in the docs) or with "gluster set" (on command line as most posts seem to use)?  

Does only one of performance/io-threads, performance/io-cache, performance/writebehind translators take effect or are they all in effect?  Are they ON by default?

We currently only installed gluster client on our clients, which doesn't have the gluster command for settings the properties.
Should we install gluster server on our clients also to change gluster client properties? 

Thank you.
Uthra

By default all gluster volumes have these capabilities built in. What is your workload and what is the nature of performance improvements that you are looking forward to?

Thanks,
