Revised TCP/IP performance benchmarks report

[Brian Eliot]

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 
(128.113.26.50) in the following files: 

  pub/bti.README        instructions for configuring and installing 
                        a Bus-Tech ELC or ELC2 interface under VM 
                        and AIX/370 

  pub/aixtcpbench.ps    performance benchmark report in PostScript 
                        format 

  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.
