IBM's Java Virtual Machine for OS/2 Raises the Bar ... Again
November 25, 1998 With today's release of IBM OS/2 Warp Developer Kit,
Java Edition, Version 1.1.7 (based on Sun Microsystems Java 1.1.7A
maintenance release), IBM sets a new standard of performance for Java
Virtual Machines (JVM). In lab testing, the OS/2 1.1.7 version showed
impressive improvements over the 1.1.6 release for both client and server
environments.
JMark, the Ziff Davis benchmark for clients, measures CPU, graphics and
text on screen performance. IBM comparisons indicated that JDK 1.1.7
performed over 40% better than JDK 1.1.6 for the cumulative JMark tests.
The results from the industry standard benchmark for server performance,
Volano, were equally impressive. All tests were performed on a Pentium 266
MHz system. On the 1-way processor, the OS/2 Warp Developer Kit, Java
Edition, Version 1.1.7 transferred an average of 385 messages per second
more than the 1.1.6 JDK. On the 4-way processor, the difference between
the two versions was nearly 600 messages transfers per second.
Independently, while 1.1.7 was still in beta test, InfoWorld conducted a
number of server side benchmark tests. The September 14, 1998 article
declared that the OS/2 JVM "caused at least a few minor tremors." The OS/2
Java Development Kit (JDK) results surpassed the Windows NT JVM by two to
three times for all but one data point and did at least that for only the
best Linux numbers.
In addition to the substantial performance improvements, this release
offers support of Eurocurrency and a multilingual installation process.
Independent software vendors (ISVs) can package the 1.1.7 Java Runtime
Environment (JRE) for the exclusive use with their applications.
This capability keeps applications immune to any changes that a user makes
to his system JVM. For example, if a developer writes and tests her
software on the Java 1.1.6 release and a user installs a later release, the
program becomes vulnerable to glitches caused by the subtle differences
between versions. By shipping a JRE with the application, the ISV is
assured that his program will run with the tested JVM.
Press Points
InfoWorld: No More Mr. Slow for Java, September 14, 1998,
http://www.infoworld.com/cgi-bin/displayTC.pl?/980914analysis.htm
In an attempt to determine if Java performed acceptably on the server,
InfoWorld conducted a number of benchmarks on Java Virtual Machines from
leading vendors. The best quote in the article is, "... if Java is
supposed to be slow, someone forgot to tell IBM." From there the article
relays in detail their testing approach and the results.
