Abstract

WRQ, Inc. commissioned The Tolly Group to compare the 3270 emulator performance of WRQ’s Reflection for IBM version 6.10 with that of Wall Data Inc.’s RUMBA Office 95/NT version 5.1A. The Tolly Group tested three areas of 3270 performance which represent common day-to-day functions of a 3270 user: File transfer, 3270 interactive, and graphics. The Tolly Group conducted a series of performance benchmarks between a PC running the 3270 emulator software under test and an IBM SNA host across three different network transports: 802.2/DLC (native SNA), via Microsoft SNA Server over TCP/IP, and via Novell NetWare for SAA over IPX. Testing was performed in April-May of 1997. 

The test results show that WRQ’s Reflection for IBM delivers better performance than Wall Data’s RUMBA Office 95/NT in a variety of network environments. Specifically, WRQ delivers faster file transfer, 3270 interactive and graphics performance in all test configurations.
