Performance with big translation file

[Cherviakov]

What is the current behavior? So we have translation files over 70Kb each, noticed that inital website loading is stalled for 5 seconds, profiling shows that this is due to calls addTranslationForLanguage and getTranslationsForLanguage, 2 times each (for 2 languages loaded). Tried to load only 1 language, but getTranslationsForLanguage still called two times and each time takes around 700ms, despite the fact that only one language data available.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below:

What is the expected behavior? Would be good to be able to remove calls of getTranslationsForLanguage which loading nothing therefore improve initial loading time for website. Also would be good to know if such big files can be handled more effeciently.
