- Well, it has turned out that we had two problems. First,
- some bridge and router setup problems. Secondly, the buffer
- size for TCP/IP on the RS/6000 was too low by default. RS/6000's
- have a command "no" for network options that allows the
- "tcp_sendspace" and "tcp_recvspace" settings to be adjusted;
- changing from the default 16K to 56K improved performance
- from 25KBytes/s to 70KB/s.
-
- There are still some things to check for better performance,
- but this is a big step up from yesterday's 5KB/s.
-
- Thanks to all who wrote in!!!
