Network Description:\n\nPretty simple network. We have a 4006 as our core with several VLANs.\nOff of the 4006 I have a PIX 515 cluster and on the other side of\nthose I have a 2600 router. That router connects to another 2600 at a\ncolo facility via two frame relay circuits. We don't own any gear\nbeyond that far end router. At the colo we have a collection of Win2K\nand Solaris sytems.\n\nThe Problem:\n\nIf I send a file from the colo to the local network..say via FTP or\nSCP...we get 140KB/sec. That's what I should get on those two frames.\nIf I send a file from the local network to any system at the colo we\nget 6KB/sec.\n\nWell, every system *EXCEPT* a single Linux server. This system gets\n140KB/sec both ways. I've tested this from local clients on the same\nnetwork and switch as the Linux system. These clients were: Win2K, Mac\nOSX, WinXP, and Solaris. They all get 6KB/sec. I tried connecting to\nboth Solaris and Win2K FTP servers at the colo. Same result.\n\nWe do absolutely no traffic shaping. None on the 4006 and none on the\n2600s. I've opened a ticket with TAC but they don't see any issue with\nthe config. The routers are as basic as you can get and the PIX is\npretty close. I'm running the latest IOS on the routers and 6.33 on\nthe PIX cluster.\n\nIf it wasn't for the Linux system working fine I'd say the colo is\ndoing some traffic shaping that they don't realize. But why would the\nLinux system work? The other clients do not that are on the same VLAN\nand physical switch.
