I am sorry guys, my estimation of sizes/preformance was wrong.
Ubuntu 19.04 / Chrome 72.0.3626.121
O3:
DEFAULT 2.0Mb 60 FPS / 22 FPS
EMTERPRETIFY 2.2Mb 60 FPS / 40 - 50 FPS
ASYNCIFY 3.0Mb 44-55 FPS / 11 - 44 FPS
Oz:
DEFAULT 1.8Mb 55-60 FPS / 22 FPS
EMTERPRETIFY 2.1Mb 55-60 FPS / 22 - 47 FPS
ASYNCIFY 2.8Mb 50-60 FPS / 13 - 35 FPS
NOTES:
- First fps number is for single dosbox instance on page (index.html?game=0)
- Second fps number is for 9 dosbox instances on page (index.html)
- Default version used emscripten_set_main_loop, I think low fps for 9
instances is because stats.js can't calculate it correctly, cause
everything work very smooth in Default mode.
- In FF every version works near 60 FPS, but game expirence is not
same (need to find better metric then FPS)
>From my point of view, ASYNCIFY is slower on ~10 FPS I tried to do
basic profiling but didn't find any spikes. I think this slowness is
related to bigger file size. Hope, option like EMTERPRETIFY_WHITELIST
can solve this problem.
ASYNCIFY have dramatic slow down (against emterpreter {in chrome?})
when you run multiple instance of same app on single page (maybe there
is some synchronization or inside chrome).
I swithced to emterpreter, becaue for now it's better. You can try
this test here:
ASYNCIFY:
http://js-dos.com/6.22/64k/index-upstream.html?game=0 (1 game)
http://js-dos.com/6.22/64k/index-upstream.html
EMTERPRETIFY:
http://js-dos.com/6.22/64k/index-fastcomp.html?game=0 (1 game)
http://js-dos.com/6.22/64k/index-fastcomp.html
Also you can download binaries here:
