We have a setup with the server having no dco, but some clients do have 2.6.5 and thus DCO enabled. Works like a charm in TCP mode (upstream/downstream both high bandwidth).
Once I switch the 2.6.5 windows client (with DCO) to UDP mode, we still have fast downstream (measured on the client, 644Mbit/s) but only 0.76Mbit/s upstream. Tried different servers: same problem. With TCP all is well, with UDP upload sucks. Disabling DCO: both with TCP and UDP all is well. So it's some sort of DCO issue -- but only with UDP. Any ideas how we could examine it further? -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netzwerk Campus Benjamin Franklin (CBF) Haus I | 1.
