[MooseFS-Users] performance inquiry

[Joseph L. <jo...@ge...>]

Hi,

I’ve been doing some tests to get an idea as to what sort of speeds I can maybe expect from moosefs, and ran into something unexpected.  From multiple clients, I can sustain 80-100MB/s per client (only tested up to 3 clients) to my 3-node cluster (3 chunk servers).  From a single client (while everything else is idle) I get the same result.  It occurred to me that the write speed to a disk in each chunk server is roughly 100MB/s, and I was curious if this seems to be the likely culprit for performance limitations for a single stream from a single client.

I’m about to try it again with SSDs, but I have a bit of time before that’s ready, and I figured I’d try to pose the question early.

Thoughts?
