Hi, I built a mirrored fs with 2 nodes, by the "Automatic File Replication (Mirror) across Two Storage Servers" example. I tested it's performance, with big files, it was good enough. If I tried to extract a kernel-source-tree (with many small files), it was extremly slow. I fingered parameters like - performance/writebehind: flush-behind to on, - option thread-count from 8 to 16, but the result was the same Extracting kernel-2.6.16.tar.gz takes 23 minutes, without glusterfs the machine extracted the tarball within 10 sec! Any suggestions? Thanks: -- ?dv, Ricsi
