Let's go on now with the WASM SPS. First remember the former tests on a 40 K solid particle SPS and the perfs I get in my Chrome : Legacy SPS : http://jerome.bousquie.fr/BJS/test/spsReference.html     (8 fps) Lighter Buffer SPS : http://jerome.bousquie.fr/BJS/test/spsBuffer.html   (7 fps) Two worker SPS : http://jerome.bousquie.fr/BJS/test/SPSWorker/twoWorkers/spsProtoWorker.html (37-42 fps) and now the WASM SPS : http://jerome.bousquie.fr/BJS/test/SPSWasm/spsWasm.html
