--- title: Speeding up Eclipse/Aptana date: 2011-05-23 12:29:49 tags: [aptana, eclipse, java] category: open source --- As you know Aptana is Eclipse. And Eclipse is a Java-based IDE which means it's not particularly a speedy one. However if you have a decent amount of ram, like 4gb, it's fairly easy to speed the Eclipse up. Find `eclipse.ini` or `aptana.ini` or other file which contents look similar. These settings are from my Linux box - I know that MacOS can get scared by higher values there; if you encounter any problems - try lowering the `Xmx` and/or others. ``` --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Xms128m -Xmx2048m ``` These settings are for the 4gb ram box, try to find the ones which suit you best. `MaxPermSize` stands for the maximum amount of the memory to be used by the Java internals, `Xms` gives the amount of heap allocated on the VM start and `Xmx` is the heap size limit. Start by upping `Xms` value as it's often too small which causes the Java VM to make lots of heap resizes on the app start.
