Perhaps it will help future sysadmins will learn from my mistake. I also saw very poor upload speeds (~30MB/s) no matter what I tried. I went through the whole route with unix-sockets and whatnot. But, in the end, it just turned out that the glusterfs itself was the bottleneck; abysmal performance for small block sizes. I found the list of suggested performance tweaks that RHEL suggests. In particular, it was the "network.remote-dio=on" setting that made all the difference. Almost 10x faster. https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.1/ht...
