You can check what happens if increasing this factor:

Many sources I find on the internet highly encourage me to leave it at 1, either because the memory-overhead is quite high or because of some compatibility issues. https://robots.thoughtbot.com/a-simple-approach-to-thread-safe-networking-in-ios-apps#extending-urlsession-to-perform-requests-in-parallel

Please try it out and check if it works. If you want me to increase it please include other sources who state what the reason is not to increase it or how it could affect other factors of any kind.

@vikassharma83021 you can create a fork of this repository, change the sample project so it includes what you want to test and then change the number in the file I showed you. This way you can test what side-effects it will have on your project or if it would work at all. (Some of the reports I found state that this helps nothing ...)

hello please tell me about this

As I'm voluntarily working on this in my spare time I don't always have as much time as a paid support-service, answering every complex question within a guaranteed 24h.

I hope you've already found out about how to fork a project, add the individual projects of the solution of this repository into yours and adding them as reference to your platform-dependent projects.

Once you've done that you can just change the number and recompile the project.
