Re: [Linux-cluster] GFS performance

A challenge we’re dealing with is a massive number of small files, so there is a lot of file-level overhead, and as you saw in the charts…the random reads and writes were not friends of GFS.


It is expected that GFS2 would do better in this area butt this does *not* imply GFS(1) is not fixable. One thing would be helpful is sending us the benchmark (or test program that can reasonably represent your application IO patterns) you used to generate the performance data. Then we'll see what can be done from there ....
