So when you launch 3.1M6 on the Mac, youll get the old, sub-optimal memory settings.

Then double-click the Info.plist file.

This should open up the Property List Editor.

Then change -Xms30M and -Xmx150M to your preferred memory settings.

Eventually I will probably swap out the 512MB chip with another 1GB chip to get up to 2GB, which is the max for PowerBooks.

BTW, more RAM definitely improves the computing experience, on any platform.

So, I like to start with 256M and make the max something like 512, yielding the arguments.

In fact, Ive found some settings (on Windows) that let me run reasonable with only a 96m heap.

Keep in mind that I run with the entire platform checked out from CVS in addition to other skunkworks projects.

As a consequence, Im in the process of moving all options from the non-standard Info.plist file to the standard eclipse.ini.

While doing this I ran into the following problems: the eclipse.ini file wasnt recognized because it was in the wrong location.

Make sure that eclipse.ini is in Eclipse.appContentsMacOS if there is a single VM argument (-vmargs) specified in Info.plist, all VM arguments in eclipse.ini are ignored.
