Two versions of Eclipse MAT is available: Based on my personnel experience, the stand-alone version seems to works better and faster than the plugin version. So I would highly recommend installing a Stand-alone version. If you are analyzing a heap dump of size say 2 GB, allocate at least 1 GB additional space for Eclipse MAT. If you can allocate more heap space then it’s more the merrier. You can allocate additional heap space for the Eclipse MAT tool, by editing the MemoryAnalyzer.ini file. This file is located in the same folder where MemoryAnalyzer.exe is present. To the MemoryAnalyzer.n i you will add -Xmx3g at the bottom.
