10GB Ethernet test
First I tested with a 8GB random File:
root@exflutcadev1:~# dd if=/dev/urandom of=/mnt/AE/exflutca1/exflutca1_testimage1_uradmom1.img bs=8K count=1000000
1000000+0 records in
1000000+0 records out
8192000000 bytes (8.2 GB) copied, 19.5786 s,
418 MB/s
If I put a link on the destination from
/mnt/AE/exflutca1/exflutca1_testimage1_uradmom1.img bs to /dev/null on thedestination and I send it from the Source /dev/zero it show the maximum ethernet speed.
