Hello,
I'm running a 1Ghz G4 with 2GB RAM with ubuntu.
It is almost impossible to use Java applications, because they are much too slow to be usable.
I tried both OpenJDK, which comes with ubuntu 9.04, and IBM Java. IBM Java is a little bit faster than OpenJDK, but in the end, both VMs are too slow to run applications with reasonable speed (examples are JOSM, jdownloader).
This is not an Ubuntu issue, but seems to be a more general problem with Linux+PPC+Java, because I experienced the same issues with other Linux-PPC-distributions.
What is the reason for this? Are there any options, to create an optimized (G4, altivec) built of OpenJDK?
I know, that 1GHz is not really high-end, but even a 9 years old P3-700MHz x86 can run the mentioned applications with reasonable speed using the sun jvm...
Thanks for your ideas :)
