temp fix: Simultaneous reads and writes from specific apps to IPoIB volume seem to conflict and kill performance.
...g data and analysis, I thought I'd follow up on my own post.
The short version:
=============
Insert gzip to compress and stream the data before sending it to
gluster fs. The improvement in IO (and application) performance is

ref/dmel-all-chromosome-r5.1.fasta -d |gzip > output.cov.gz
inserting the '| gzip' increased the app speed by more than 30X
(relative to not using it on a gluster fs; however it even improved
the wall clock speed of the app relative to running on a local
filesystem by about 1/...
