I don't have a patch to offer but the entry point for the 
self-heal-daemon code itself is in syncop_mt_dir_scan()  which gets 
called for each of the 3 sub folders under /brick/.glusterfs/indices/ 
(for each brick). It uses gluster's synctask framework to readdir the 
entries in these sub folders, and eventually calls afr_shd_index_heal() 
for each of the entries. So if you think shd is stuck, maybe you can see 
at what point it is stuck - perhaps while afr_shd_selfheal() for a given 
entry is stuck on an inodelk held by the client. Maybe look at the 
pstack of the shd process.

I also see from the profile info on your first email that XATTROP fop 
has the highest latency. Can you do an strace of the brick processes to 
see if there is any syscall (setxattr in particular, for the XATTROP 
fop) that is taking higher than usual times?

For the slow ls from the client, an ongoing selfheal should not affect 
it, since readdir, stat etc are all read-only operations that do not 
take any locks that can compete with heal, and there is no hardware 
bottleneck at the brick side to process requests from what you say. 
Maybe a tcp dump between the client and the server can help find if the 
slowness is from the server side by looking at the request and response 
times of the FOPS in the dump.

Since you're saying hardware is not saturated despite increasing the shd 
threads and wait-queues, you could try increasing 
performance.io-thread-count on the brick side from the default 16.
