Hi all, I read the posting from Jeremy and did some tar tests myself. The hardware of my test servers is rather old. Two Dell 2550 which have an internal network via crosslink (100Mbit) for the glusterfs communication. I'll change to the other NIC (1Gbit) and run the test again tomorrow. The results were pretty disappointing. I tar-ed the kernel sources which is around 80 MB. The resulting tar file had 11 MB. Unpacking this on ext4 lasted a few seconds while on my glusterfs-Raid 1 it took more than 8 minutes! Then I took the config of Jeremy and got around 5 minutes for unpacking it. Even if I have new and fast servers with 1Gbit or better 10Gbit ethernet for glusterfs I fear that the performance is still too poor. At least if it comes to reading/writing lots of tiny files from lots of clients. Mail- or db-servers come to mind. What do you think? Regards, Oliver
