Hi all, I ported a fluid simulation C++ code (command line program) with emscripten and it works quite fantastic. I never thought JS could run that efficiently. However, to re-run my program I wrapped the compiled version in a function (with pre/post.js) to reset its state. That usually worked nice, but recently I get at first an awesome performance from FF (~0.3 native speed!), but after a reset it suffers a drastic performance breakdown of a factor of 20.
The site is http://gaia.respawned.com You can observe it just by clicking "Run" in the Run tab, the sparse matrix mul+add performance is measured thoroughly. At first run: Performance (mul+add): 0.377445 GFlops After "Reset" (calling gaia_create() again in the worker): Performance (mul+add): 0.0187213 GFlops On a recent Chrome I do not get a difference, always around 0.26 GFlops. Thanks for your help, Christian PS: Native gcc -O3 : 1.17 GFlops. -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
