I am interested in trying this tool. Before I do I was wondering if there was a limitation to the size of the .DMP files I could open. I will be profiling an application that uses a high amount of memory and will need to be able to profile such dumps.
In version 5.0, the 4 GB limitation has been removed. In this version the size the snapshot is only limited to the amount of available memory on the machine, but working with a very large snapshot will be rather slow.
We have tested to import an 18 GB memory dump with about 250 million instances in version 5.0 on a machine with 32 GB memory. The import worked correctly, but it was slow to work with the snapshot, and we did get a few out-of-memory problems when investigating root paths and viewing instance graphs (the out-of-memory problems did not stop or crash the profiler, but the information could not be presented).
