Right. I had a pleasant experience with TPTP not so long ago and it worked with Harmony. Even though I've managed to run Harmony+TPTP only in interpreter mode, the information I've gathered was really valuable.
And so: 1. (Xiao Feng's idea) -Xverbose:gc may give you an idea what's going on with Java heap in general 2. TPTP/HeapProfiler may give you pretty good insight down to exact allocation sites, liveness info, rate of allocations and stuff 3. Jitrino Internal profiler [1] may give you hints about allocations too, and AFAIK you may run it even with aggressive optimizations Thanks, Aleksey.
