Hopefully this post can change your mind and help you experience the wonderful world of Eclipse (ok, I am being a little dramatic here).

The thing is, they probably never experienced the full potential of Eclipse – a pity. It’s Java, so it is supposed to be slow and they just go and hate it and sing how X-Code is great. I bet many people not having experience with Eclipse on other platforms would think this is normal.
Working with Eclipse on OS X felt horrendously slow! I had already noticed this nuance in the past and I thought that the Eclipse is just not meant to fly on Mac's (oh well…), especially when there are so many different distributions for OS X, it signals that the project is in a shifting phase basically (it is shifting from Carbon to Cocoa) and that you should expect all kinds of problems. These commands can be done through command line: eclipse -vmargs -Xmx256M įor further information on this topic, here is the official Eclipse link to where I found my information.If you’ve been experiencing horrendous performance of Eclipse on OS X, or maybe you even did not know that Eclipse actually can run very fast, you’d be surprised to learn that apparently it is very easy to make Eclipse run 4-5 times faster on OS X with proper settings to your eclipse.ini file. The problem was that the JVM was restricting the amount of memory available on the heap so arguments had to be passed to the VM to alter this. ini file where Xms is minimum space and Xmx is maximum space. for Mac: located under Eclipse menu item), open the Java section, click on Installed JREs, click on the JRE being used (probably will be jre6), click on the Edit… button, and insert this into the Default VM Arguments: -Xms256M -Xmx512M This then brought me to try the second method of fixing this problem…Ģ) Inserting VM arguments into your JRE: while Eclipse is open, open up Preferences (for Windows: located under Window menu item. ini file showed a max of 512MB while my program reported only 128MB. Note: to check your max available heap space in Java use this line of code: (().maxMemory()) Įclipse was actually not limiting my heap space because my.
ini file it was actually showing a max heap space larger than what was showing in my program. Changing the 256m to something bigger like 512m should increase the heap space Eclipse supplies. What this is showing is that the minimum heap space (-Xms40m) is set to 40MB and the maximum heap space (-Xmx256m) is set to 256MB. ini file you will see some options like this: -showsplash

For Mac users just right click the executable file and choose the Show Package Contents option. ini file: This file could be found in the same folder as your Eclipse executable file. Click here or the Read More link for solutions…ġ) Changing Eclipse’s.
So, after digging around a bit on Google I found two simple solutions that I continued to run into. When dealing with a huge amount of data and objects in a large hash array of trees, heap space can run out pretty quick. It just so happens that the heap space that is allocated for my programs in Eclipse on my Mac at home is less than what is supplied for my work laptop, thus making my program crash at home and not on my laptop. Ran into the problem of running out of heap space when running my program on Eclipse the other day.
