get_historial_klines is too slow

Hi, I created a function that calls get_historical_klines() for all symbols on binance. But on average calling get_historical_klines() for one symbol takes about 2~3 seconds, and the function takes more than 5 minutes to complete the actions.

Is there any way to speed up this process?


I have same issue. Is there any solution ?

This question is not related to the Binance API. I suggest contacting the owner of the library you are using.

Threads, in javascript you can use Promises
