Hi, I'm testing a storage system and different network settings and I'm faced with a strange phenomen. Doing a mkfs.ext4 on the centos server lasts 11 minutes. The same mkfs.ext4 command on the debian installation is done in 20 seconds. It is formatting a 14 TB 10Gbit ISCSI Target. It is the same server. Centos and debian are installed on different internal harddisks. Any

Help please- I am running 3.3.1 on Centos using a 10GB network. I get reasonable write speeds, although I think they could be faster. But my read speeds are REALLY slow.

Here are some additional details:
