With GlusterFS, almost all the processing is in the client side. This includes replication. So, when you have "replica 4", the client will be duplicating all transactions 4 times, synchronously. Your 1G ethernet just became 256M. I don't know how much "in production" your environment is. You might want to try the 3.4 beta with the qemu glusterfs driver (using libgfapi.so). You should get a good speed bump, by bypassing the FUSE interface. Also look into the write-behind and read caching translators for the volume itself. -- Mr. Flibble King of the Potato People
