I realize that m2e 1.4 has not been officially released yet but I just pushed some rather big changes to master/1.5 branch and want to ask m2e users to help me test them.
As I explained in the past [1], m2e requires about 1M+ of memory for each opened workspace maven project. Although memory is cheap and getting cheaper, using large heap results in noticeable garbage collection overhead, which becomes apparent with very large workspaces that require 2G+ of heap. This was getting rather annoying for my nexus development workspace where I have 300+ projects, so I decided to rework how m2e manages its various memory caches. The first change I just pushed limits number of long-lived MavenProject instances to just 5 (five). For my workspace and development habits this reduced Eclipse heap requirements from ~2.5G to well under 1G without any noticeable side affects. This, of course, does not mean there are no problems with this change and I'd like to see if other users with large workspaces can give it a try and provide any feedback, good or otherwise. As usual, installation repository URLs can be found on m2e download page [2].
