<h3>Introduction:</h3>
|
|
<p>Much has been talked about recently with Sun's decision to release an
|
|
official port of Java for Linux. This study was done to compare the
|
|
actual performance of the <a href="http://www.blackdown.org">Blackdown</a>
|
|
Linux Port with the <a href="http://www.FreeBSD.org/java/">FreeBSD Port</a>
|
|
of the &jdk;.</p>
|
|
|
|
<h3>Summary:</h3>
|
|
<p>The Linux port is faster than the FreeBSD port, even when the JITs are taken
|
|
into account. For graphic intensive applications, all the FreeBSD tests are
|
|
faster than the Linux, with FreeBSD/TYA being the fastest overall. Comparing
|
|
the Linux port with the FreeBSD port, each with no JIT running, FreeBSD is
|
|
faster. We may conclude that, when running on FreeBSD, the JIT design
|
|
makes the difference in speed. </p>
|
|
|
|
|
|
<h3>Testing Methods:</h3>
|
|
<p>All tests were run on FreeBSD 3.4-RC (Tue Dec 7 09:14:51 EST 1999) on a
|
|
Dual Pentium 200 SMP machine with 128 Megs RAM. Tests were conducted with
|
|
Pendragon Software's <a href="http://www.webfayre.com/pendragon/cm3/index.html">
|
|
Caffeine Mark</a> 3.0 software using the "Run all tests locally" option.</p>
|
|
|
|
<h3>Software Versions:</h3>
|
|
<p>The following is a list of the software used in this test:
|
|
<br/>FreeBSD JDK 1.1.8
|
|
<br/>Blackdown's JDK 1.2.2-RC3 (under Linux emulation)
|
|
<br/><a href="http://www.shudo.net/jit/">ShuJIT</a> 0.3.13
|
|
<br/><a href="ftp://gonzalez.cyberus.ca/pub/Linux/java/tya15.tgz">TYA</a> 1.5

<h3>Conclusion:</h3>
|
|
<p>Newer versions of the software used in the tests above been released since
|
|
this test was conducted. For this reason, these tests will be run again in
|
|
the near future to see if the newer JITs for FreeBSD alter the results.
|
|
The same JITs will be used with the Linux JDK to test their effects as well.</p>

<h3>Tester:</h3>

|
<p>These tests were conducted by Patrick Gardella <a href="mailto:patrick@FreeBSD.org">patrick@FreeBSD.org</a> in December 1999.</p>
