I'm the dork who did the port of BNU UUCP to the RS/6000 while contracting at IBM Austin. For grins and giggles, I connected a couple TrailBlazers (T1500s, I believe) and did some throughput measurements. My figures between two RS/6000's were a *lot* better than 1500bps but didn't compare to the figures my friends/neighbors were seeing between NCR Towers, DELL boxes, and TI BS1500s. The real killer is connecting to an IBM RT because VRM had a nasty problem with high-speed UUCP connections overflowing the i/o buffers -- consequently VRM handled the overflow by sending either a SIGHUP or SIGINT to uucico which caused the connection to die for mysterious reasons... The "fix" for that APAR was to slow down uucico rather than speed up VRM. No shit. What's your system configuration? What else is running on the system (number of users, applications, etc)?
