Having a reification in Moose of 100 versions of Mondrian for example :-) Just answering the question 'Which classes and methods of Mondrian have changed more than 10 times since the day Mondrian was born?' cannot be easily done without a lot of memory Alexandre On 24 Nov 2011, at 03:27, Francois Stephany wrote: > I'm wondering: how big is a dataset > 500MB ?

We are doing data conversion with Moose. Raw data is 740 MB. No 64-bit means being forced to make decisions early, and therefore wrong. It also forces us to do some batch processing. We're very lucky the customer has a good idea on what data to keep. Stephan

Re: [Pharo-project] experience with large images?

by Tudor Girba

I guess Alex talks about a Moose image. With Moose we can easily get to quite large images with millions of objects. For Windows, we indeed had a problem with the VM that Igor fixed. At that time, the problem appeared in images of over 200MB that could not be reopened (could be built, but once closed could not be reopened). I do not know what the status is with 500 MB. But, I also guess that Alex refers to the default values for memory when running the VM. Is that correct Alex?
