Hi,

First, the performance measurement between i386_linux and x86_64_linux 
versions of ECLiPSe is for a few benchmark programs. I have heard from 
others that they get significantly better performance (I think about 
30%) for x86_64_linux, so which is faster can be dependent on your program.

You need to run RUNME script in the Unix binary distribution to install 
it, and if you are installing the i386_linux version on x86_64_linux, 
you may need to change some of the default settings the script ask you 
about, in particular the first question, which machine achitecture you 
are installing for, which should of course be i386_linux and not 
x86_64_linux.

You need to use 32 bit Java with the 32 bit ECLiPSe. The binaries for 
the JavaInterface is compiled against 32 bit Java. There is a check that 
the Java platform is the expected one when the Java interface is started up.

Cheers,

Kish
