Currently there is not a proxy server in the network, although when using some of the test on dslreports.com there is a message about compression being used for the upload and to remove proxy settings. I have also been testing using FTP on a *nix server as well. Both the server and PC are connect to a Cisco 2960 switch in the headend that is connected to the 7200 router. I can transfer ftp at about 80Mbps between the PC and the server, so they are not IO bound. The Site I am testing with is a ftp server located in a colo facility that we use and has sufficient bandwidth. This circuit is clean in the sense of not having CRC, framing or other errors but this is a new circuit and we have never gotten more than 5Mbps out of a single session (flow/ip) across the wan. I would have to double check the mtu, but it is currently the default. -- Brian Raaen Network Engineer braaen () zcorum com On Monday 07 April 2008, Brian Raaen wrote:

using a full OC3 circuit. I am doing fine on downloading data, but
uploading
data I can only get about 5Mbps with ftp or a speedtest. I have tested against multiple networks and this has stayed the same. Monitoring Cacti graphs and the router I do get about 30Mbps total traffic outbound, but individual (flows/ip?) test always seem limited. I would like to know if anyone else sees anything similar, or where I can get help. The assistance
I
have gotten from Sprint up to this point is that they find no problems. Due to the consistency of 5Mbps I am suspecting rate limiting, but wanted to
know
if I was overlooking something else. -- Brian Raaen Network Engineer braaen () zcorum com
