File transfer speed limit
Posted on 2009-02-18
I am trying to transfer the vmdk file from a VMware host, (130 GB) using SCP transfer protocol.
The highest speed I get is around 12 MB/s
Dell PowerEdge 2950 Server, with onboard Gbit NIC's (VMware ESXi)
Dell Optiplex 755 with Intel Gbit NIC (Windows 2k3)
The computers are connected directly by cable. NO Switch
I know it is impossible to use 100% of the bandwith available, but 12 MB/s is roughly about 10% of a Gbit bandwith.
I have, for testing purpose, tried transferring a large file between 2 Windows XP's with the same result. around 12 MB/s.
Is this a limitation to the file-system ? or an issue when copying large files ?
