A report first made available in April detailing the TCP/IP
performance of AIX/370 and TCP/IP for VM has been revised to include
data for the IBM 3172 Model 1 Interconnect Controller and the
Bus-Tech Ethernet LAN Controller Model 2 (ELC2) FASTCETI emulation.
The revised report may be obtained via anonymous FTP to aix.rpi.edu
(188.8.131.52) in the following files:
pub/bti.README instructions for configuring and installing
a Bus-Tech ELC or ELC2 interface under VM
pub/aixtcpbench.ps performance benchmark report in PostScript
pub/aixtcpbench.1403 performance benchmark report in line printer
format (ASA carriage control)
The 3172-1 benchmarks were performed at all three supported channel
data rates and achieved FTP throughputs in the range of 575-650
kilobytes per second. The ELC2 FASTCETI throughputs ranged from
885-950 kilobytes per second. These results were achieved using
AIX/370. TCP/IP for VM (5798-FAL) results for the 3172 were in the
range of 250-310 kilobytes per second.
Our thanks to RPI's Engineering Computing Services department for
making the 3172 available for the benchmarks.
