We are running our webapp on a gluster mount. We are finding that performance is a lot slower than local disk. We expected it to be slower but not this much slower. So, I am looking to you for some guidance on what to do. IE: Not run off the gluster mount or change config settings, etc.
Here are some numbers on performance:
Gluster Mount html:
