This would be pretty impressive, around 150000 baud! I assume you mean
15000 baud.

Here's some test results I got:
All tests are between 2 IBM RT/PC's running 4.3 BSD UNIX with
header compressed SLIP and using Dickens Data Systems 8 port adapters.

Microcom 3296hs BETA: PROM LEVEL: GOLD: 8/31/90, SERIAL BAUDRATE: 38400
PING test...
----dagorlad.watson.ibm.com PING Statistics----
103 packets transmitted, 102 packets received, 0% packet loss
round-trip (ms) min/avg/max = 342/355/382
FTP test: default tcp_recvspace * 1024 *
FILE DESCRIPTION DIR SIZE THROUGHPUT
---- ----------- --- ---- -------------
one * 1024 * best case, all 1's GOLD get 133K 3.2 Kbyte/sec
/etc/hosts 1024 ascii unix host table get 200K 2.8 Kbyte/sec
gigiplot 1024 binary, application get 50K 2.1 Kbyte/sec
vmunix 1024 binary, UNIX kernel get 1M 1.7 Kbyte/sec
hosts.Z 1024 worst case, precompressed get 69K 1.1 Kbyte/sec
