I am currently using JRE in Eclipse. I am wondering if using JDK is going to speed up Eclipse. I use Eclipse only for PHP development, and not for any Java-related work.
Using the JDK won't speed up Eclipse. If you aren't doing any Java development work, there's no reason to use it.
Download a JDK if you're doing real Java development as you'll need it for that. If you're doing C/C++, PHP, or something else, you might never need it and can just use a Java Runtime Environment (JRE). Eclipse already comes ready to use that and probably already works without you doing anything.
To speed up eclipse,keep JDK on a RAM disk.It just needs 300mb space and it doesnt required by other programs.
