We usaually see that we have a seperate Software for 32 bit and 64 bit O/S
Also people say that 64 bit machines can run most of 32 bit software albeit performance increase is not guaranteed.
My search into hte ranch gave me one nugget that is
----------
"By default jvm runs in 32 bit mode. I think you have to pass an argument
( -d64 ) into the JVM to make it run in 64 bit mode. " (Thanks Rich)
-----
My question is if we need to recompile our
java classes and jar files (and regenerating this byte code) to get them to work efficiently. Or it is not required as it is the jvm which is handling the execution.
thanks for inputs.
