My search lead me to another better approach to solving this problem.

For instance, the system monitor shows that eclipse is only consuming 500Mb RAM, now what difference will it make if I provide 2048m to -XX:MaxPermSize? System Monitor The main issue here is that the underlying linux won’t provide the required boost to eclipse no matter whatever the parameters you provide. Since Eclipse is pretty much a RAM hungry monster, feeding it with lots of RAM should surely make it run fast, right? Wrong! Until recently I had spent a lot of time tweaking those parameters, but no substantial performance could be gained (though I have 4GB of RAM with i3 which is not a bad configuration).

If you are still one of those people who are frustrated with the crawling speed of eclipse IDE (especially after the recent clunky releases of Juno/Kepler), then you are in good company! Most of the advice you might have read until now for speeding up Eclipse must have involved tweaking the following parameters in eclipse.ini file:
