On an international line from Australia to USA (nwnexus) my trailblazer
consistently reported (via the appropriate S register) an instantaneous
bit rate of 14000 bps yet I can only get around 450 bytes/second
throughput. Listening to the modem there seems to be a fair bit of
idle time. I can only conclude that the loss of performance is in the
machines rather than the modems. My machine is a 20MHz 386 with Stallion
serial I/O (super smart) at 19200. Nwnexus is a VAX 750 with unknown
serial I/O at 9600 and unknown loading. I did enquire about the hardware
and system load but got no response. From my own experience a VAX 750
runs out of puff in the CPU department very easily. Anyone got any
comments?
