IBM Releases Fastest SDK For Java 6
IndioMan writes "IBM is releasing an SDK for Java 6 and is sponsoring an Early Release Program to gather feedback from the Java community. Product binaries and documentation are available for Linux on x86 and 64-bit AMD, and AIX for PPC for 32- and 64-bit systems. In addition to supporting the Java SE 6 Platform specification, IBM's SDK also focuses on platform stability, performance, and diagnostics. It's tops on every benchmark."
Sun didn't want to delay the launch of Java 6, so it's Java 7 that's open source.

Funny, but even Sun's JDK blows Perl out of the water.
Why did the parent modded as troll? It's quite true. For example, look at The Computer Language Shootout. Sun's JVM is much faster than Perl in almost every benchmark except for startup times. Perl's memory consumption is somewhere better, but not even close to the same degree that Java is faster.
Those benchmarks are based on Java 1.5, too. 1.6 is even faster.

There are 2 ways to get a 32-bit Java plugin running under a Linux/AMD64 environment (BTW, AMD64 is the official arch name implemented by AMD and Intel, x86-64 has been officially abandonned):
Of course, since Sun has open sourced Java, a 64-bit Java plugin is likely to appear soon.
Scimark wasn't even close:

Higher scores are better. Both run on AMD X2 5000+
Sun VM stomped on IBM's. That wasn't true with earlier VM's. IBM used to smoke Sun on scimark. Maybe there's more development to be done.
That's not true. The source code has already been opened as a project:
https://jdk.dev.java.net/
The fact that they haven't made their first release from that product changes nothing.
The slow performance of Eclipse is not due to the JVM, it's about the SWT library and it's bindings with the native libraries. There was an SWT port called SWT Fox that quickened things up a bit. It doesn't seem to be maintained anymore, but the performance speedup was very noticable. Changing the VM probably won't make the slightest of difference.
That cost me two moderations. Why aren't moderations in a discussion depended on the *branch* of the discussion? Oh well...
In the meanwhile, we've still got customers stuck on 1.3, because our "write once, run anywhere" code doesn't run on 1.4, and it's too much effort to puzzle out why because Sun's runtime is just such a mess.
h tml
There could be several reasons why Java 1.3 code won't run on 1.4. One is if you use sun.* or com.sun.* packages directly, which is funcamentally against portability guidelines. Another could be real incompatibilities. There are very few incompatibilities between 1.3 and 1.4. They are listed here:

If you keeping customers from using Java 5.0 or Java 6.0 because you can't sort this out, you are keeping them from major performance and functional improvements.
