Gluster users - Jun 2010 - how much has performance improved since 2.x?

Greetings,

I was curious if the 3.x glusterfs has made any significant write 
performance headway (especially when dealing with small files).  Last 
time I was testing 2.x, I had to write glusterfs off due to poor 
performance (previous config/performance-stats can be accessed in list 
archives if curious).  Did anyone notice *dramatic* improvement when 
switching to 3.x?

Thanks,
Michael

Michael - 
We are constantly working on improving performance, the 3.x release was no
exception. The current version, 3.0.4 will perform significantly better than any
2.x release. The 3.0.5 release, just around the corner, includes three patches
specifically designed to improve small file performance -

selective readdirp - http://patches.gluster.com/patch/3203/ 
dht lookup revalidation optimization - http://patches.gluster.com/patch/3204/ 
updated write-behind default values - http://patches.gluster.com/patch/3223/ 

The current 3.0.5 beta is here -
http://ftp.gluster.com/pub/gluster/glusterfs/qa-releases/glusterfs-3.0.5rc5.tar.gz
. All the usual warnings about beta releases apply, no production, no important
data.
For users that can't use the GlusterFS client we have made some huge
performance related leaps forward by writing our own NFS server, the gNFS.
Currently at RC6 the engineering team is beta testing gNFS with several
customers now. With gNFS small file performance has been improved 3x-5x over
uNFS.

The gNFS server -

. All the usual warnings about beta releases apply, no production, no important
data.

I hope you will give 3.0.4 and 3.0.5 a try and let us know how it goes. If you
need any help please feel free to get in touch anytime.



Thanks, 

Craig
