A possible explanation for this could be JIT Deoptimization. Deoptimization
happens when
Correction regarding the run-queue, this is not completely correct, :S .
But the stalled cycles and memory accesses still holds.
Sorry for the misinformation.

I ran Linux perf and also watched the run queue (with vmstat) and your
bottleneck is basically memory access. The CPUs are idle 80% of the time by
stalled cycles. Here's what I got on my machine.
Intel Core i7 4 cores with Hyper thread (8 virtual processors)
16 GiB of Memory
Oracle JVM

Hi,
http://youtu.be/xiqWclsXdcc
I just wanted to share a "live" performance with Newtonian and Quil. The
video has better frame rate than the first one, which shows better
the fluidity of the particles , I changed the colors of the particles and
also increased their size.
Instead of recording
,
or something similar, probably I would've never started it.
:) Thanks

I've been working in a particle system using Quil for rendering, which I'm
calling Newtonian for now ;) , just to practice some of the concepts of
protocols and defrecords. The project is still WIP. Any feedback will be
appreciate it.
