Hello all, after playing around for some weeks we decided to make some real world tests with glusterfs. Therefore we took a nfs-client and mounted the very same data with glusterfs. The client does some logfile processing every 5 minutes and needs around 3,5 mins runtime in a nfs setup. We found out that it makes no sense to try this setup with gluster replicate as long as we do not have the same performance in a single server setup with glusterfs. So now we have one server mounted (halfway replicate) and would like to tune performance. Does anyone have experience with some simple replacement like that? We had to find out that almost all performance options have exactly zero effect. The only thing that seems to make at least some difference is read-ahead on the server. We end up with around 4,5 - 5,5 minutes runtime of the scripts, which is on the edge as we need something quite below 5 minutes (just like nfs was). Our goal is to maximise performance in this setup and then try a real replication setup with two servers. The load itselfs looks like around 100 scripts starting at one time and processing their data. Any ideas? -- Regards, Stephan
