How to reduce Skype load?

Question

Skype

Recently, when Skype disabled the ability to use older versions, there was a problem how to reduce the load on RAM when opening more than 100 Skype windows.
Since at the moment it is not realistic to run more than 50 pieces, I use:
System: Windows Server 2010
RAM: 64 GB

Answer 1

Tried redirecting to Virtual Box. There should be less there.

Answer 2

1. Apparently, write to Skype and ask them to refactor the code, i.e. that their Skype began to consume less RAM. This is their application ..
2. Increase RAM
3. Reduce / distribute the number of windows

Alternatively, you can try to communicate through bots, t .e. there will be 100 bots (instead of windows)
