By default, as of the 2019-09 release, Eclipse will use up to 1024MB of memory. This seems to be sufficient for most of what we do.
In some older versions, the default may be as little as 512MB of memory, which is probably too low If you need more, for example if you have a lot of large projects open at once. To adjust this, edit , this can be adjusted. Edit your eclipse.ini
file and adjust the -Xmx###m
setting appropriately (768 or 1024 is good). On Windows and on most Linux distributions the eclipse.ini
file is located in the same directory as the eclipse Eclipse executable. On macOS, control-click on the executable, select Show Package Contents and then go to either Contents/MacOS/eclipse.ini
or to Contents/Eclipse/eclipse.ini
.
