Now i'm using a bonded gigabit (2x1GB) on every server but i'm still stuck at about 15-30mbit/s when extracting the Linux kernel. Total extraction is still about 10minutes. Something strange is going on, on a dual gigabit connection (2000mbit) I'm expecting to reach hundreds of megabit (200-300), not tens (15-20) # dd if=/dev/zero of=/mnt/glusterfs/zero4 bs=1M count=1000 1000+0 record dentro 1000+0 record fuori 1048576000 byte (1,0 GB) copiati, 88,2981 s, 11,9 MB/s # gluster volume info gv0 Volume Name: gv0 Type: Replicate Volume ID: 2a36dc0f-1d9b-469c-82de-9d8d98321b83 Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: 77.95.175.112:/export/sdb1/brick Brick2: 77.95.175.113:/export/sdb1/brick Brick3: 77.95.175.114:/export/sdb1/brick Options Reconfigured: performance.cache-size: 2GB performance.write-behind-window-size: 2GB features.shard-block-size: 64MB features.shard: on transport.address-family: inet performance.readdir-ahead: on nfs.disable: on _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
