In my testing I only see 2 files getting healed at a time per replica pair. I would like to see this be multi threaded(if its not already) with the ability to tune it to control resource usage(similar to what we did in the rebalance refactoring done recently). If you let me know the BZ # I'll add my data + suggestions, I have been testing this pretty extensively in recent weeks and good data + some ideas on how to speed things up.<br></span>
Good news is we already have a WIP patch <a href="http://review.glusterd.org/10851" target="_blank">review.glusterd.org/10851</a> to introduce multi threaded shd. Credits to Richard/Shreyas from facebook for this. IIRC, we also have a BZ for the same but the patch is in rfc as of now. AFAIK, this is a candidate to land in 3.8 as well, Vijay can correct me otherwise.<span class=""><br>
