CPU/RAM heavy application run on GraalVM #1111
Description
Hello, guys. I'm working on Beam project (https://github.com/LBNL-UCB-STI/beam) and it's CPU/RAM intensive simulation. Made an experiment when run simulation on GraalVM. All the runs were on the same AWS instance (m4.16xlarge - 64 cores, 256 Gbytes RAM), Java maximum heap was limited to 168 GBytes. Under iteration time in comparison table I've meant the time for the agent simulation (CPU intensive, there is some IO there, but it happens asynchronously).
