Hi Ben,<br>
Uploaded a new patch here: <a href="http://review.gluster.org/#/c/9657/" target="_blank">http://review.gluster.org/#/c/9657/</a>. We can start perf test on it. :)<br>

Thanks Ben. RPM is not available and I am planning to refresh the patch in two days with some more regression fixes. I think we can run the tests post that. Any larger data-set will be good(say 3 to 5 TB).<br>
<br>
Thanks,<br>
Susant<br>

I have some rebalance perf regression stuff I have been working on, is there an RPM with these patches anywhere so that I can try it on my systems? If not I'll just build from:<br>
<br>
<br>
git fetch git:// <a href="http://review.gluster.org/glusterfs" target="_blank">review.gluster.org/glusterfs</a> refs/changes/57/9657/8 && git cherry-pick FETCH_HEAD<br>
<br>
<br>
<br>
I will have _at_least_ 10TB of storage, how many TBs of data should I run with?<br>
<br>

This is interesting. Thanks for sharing & well done! Maybe we should attempt a much larger data set and see how we fare there :).<br>
