This might be a dumb/naive question, and if it is please excuse me :)

This might be a dumb/naive question, and if it is please excuse me 🙂

I have a brand new machine with the following specs:

This machine has a 64 bits architecture.

On my previous machine, I used to install 32 bits versions of Eclipse and run it using a 32 bits JRE, and my current Eclipse setup works perfectly on the new machine.

I tried to install a 64bits version of Eclipse, and run it with a 64 bits JRE, and I am wondering if there are any compelling reasons to switch to this kind of setup or stick to my existing install. I guess that I would have to reinstall all the plugins, and maybe find that some of them are not compatible with the 64 bits version of Eclipse.

So far, the 64 bits version seems to need quite some more RAM than the 32 bits version, which is something that I expected, but nothing seems to have improved.

Thanks for your advice!

    In general I use 64-bit Eclipse without problem, but there can be issues around plug-ins such as:

    • Adobe Flash Builder only works with 32-bit
    • The Subversion plug-in Subclipse needs a native 64-bit version of Subversion installed separately

    There may be more but those are the ones I’ve encountered in the past.

    Moving to 64-bit gives you access to more addressable memory but it won’t speed anything up, in fact it might reduce performance in some cases (but nothing I see as significant to what I do).
