Whis the following:

# 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:
features.shard-block-size: 64MB
features.shard: on
transport.address-family: inet
performance.readdir-ahead: on
nfs.disable: on

i'm still stuck at 10m35.507s

I only have 1GB connection, thus 1GB/3 should be the maximum speed.
1000/3/8 = about 40MB/s

# du -sh linux-4.7-rc6
632M linux-4.7-rc6

632M / 40 = 15.8 seconds.

It should take 15.8 seconds to extract.
