Alameda, CA Lines: 18 Summary: 500 chars/sec limit? When I run uucp/kermit at 9600 baud between my 7300 and another machine, about the best throughput I can get is around 500 chars/sec, or ~4800 effective baud at 9 bits/char. Curiously, if I have two channels running between the two machines (using a combo card), _each_ will run 500 c/s. Has anyone got any ideas on how to improve this? What limit am I running into? Since I do backups from the 7300 to the other machine, and it take about 20 hours to do one with this throughput, even marginal gains would help. (If necessary I can write my own transfer software using VMIN/VTIME stuff. Is it worth the effort?)
