Performance issue

[raphaklaus]

Converting ttf to woff2 takes 30~45 seconds. Is there something planned to avoid this performance issue?

You are probably using the JS fallback. Setting up your env to run the native add-on will certainly speed up the build.

Feel free to suggest Emscripten configuration improvement if you think the JS fallback may be built better.

Hello, guys. We are using ttf to woff2 inside Electron application (mac os platform) and also having the performance issues. You've mentioned that JS fallback can be the reason. If so, can you give us advice, what can be done to avoid getting to this fallback. Some library or Electron environment settings maybe? Any thoughts or suggestions? Because being run as CLI tool ttf2woff2 gives us outstanding conversion speed, which we are missing inside Electron app.

I don't have any experience in Electron apps building atm but you may looks at this module setup. See https://github.com/nfroidure/ttf2woff2/blob/master/binding.gyp for example and adapt it to your own build.
