Interesting. One also has to wonder about scalability. Even small differences in resources can add up pretty quick under high volumes. Did you see any evidence on how this might shake out?

Best I can recall, we compared the timings after the JVM was built (first invocation of the Java txn took about 5 seconds; pretty much sub-second after that). The COBOL was just enough faster to be noticeable at the terminal. The txn retrieved and displayed one record from a VSAM KSDS. Best recollection from TMON data is that the COBOL ran about 20% - 30% faster than the Java. -jc- NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
