We have an issue with regard the to the bandwidth we are able to realize on an FTP as well as RDP between our Hyderabad/India office a client location in the USA. We are using Cisco VPN connection between the two locations. We have a 10 Mbps (10 mega bits per second) connection, but when we transfer files between the locations over RDP and FTP, we are never able to get more than 40 KBps (40 kilo bytes per second – or 320 kilo bits per second or 0.32 mega bits per second), even when no other machine on our network is active.
We have already checked our firewalls, switches and updated the VPN software. We have also tried to switch to a different TCP port. We also tried to increase the MUX packet size to 1500 on the Windows. Nothing is working, even when we have one machine directly connected to the 10 Mbps link, and we are not able to realize 0.32 Mbps for the file transfer. However, we see that higher bandwidth is available for other ports/services (like HTTP), we are able to realize better bandwidth, up to 250 KBps
Please help us in achieve more speed both on FTP as well as file copy over RDP.
Thanks in advance.
