Any tips on optimizing for poor connection speed?

Apologies if this isn't the proper place to ask, but I'm looking for some tips on how to improve my app's networking.

I have a mobile app that currently uses multiple dedicated threads, each with their own io_context. When I'm on wifi, everything completes instantly and without issue. When I'm off wifi using 5G, tasks consistently timeout (I have a 30 second timeout). I currently will submit potentially over 1000 requests on a single ioc in a single thread. It seems to be too much when on a slower connection.

Will there be any benefit to spawning a thread pool and sharing a single io_context across them and submitting new tasks using post() instead of my current model?

Does io_context have any kind of internal queue that'd make it more efficient at managing tasks when there's some that are already in flight?

Any help would be appreciated.

io_context support multi-thread, and consider asio::thread_pool instead of asio::io_context. I think it is difficult to provide an opinion without code or further description.
