Latency limits TCP throughput. I am working with an application now that is maxing out at 4-5Mbps over a link with 80-120 ms latency cross continent. One way to improve throughput is to adjust buffers/window sizes on the sender/receiver machines and/or use a WAN acceleration product like Cisco WAAS.

I have gear in Amsterdam and in San Jose. Pushing log files from Amsterdam to San Jose through rsync seems to top out at 7Mbps even though the box doing the push is pushing much more out to the Internet. If I run several rsync's it goes quicker so I know I have the bandwidth. What's limiting me? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ Note: This message and any attachments is intended solely for the use of the individual or entity to which it is addressed and may contain information that is non-public, proprietary, legally privileged, confidential, and/or exempt from disclosure.
