Memory consumption by Viber

Negative Comment by RoverWhite
about Viber Sep 2016

Working on Windows 7 x64 Viber consumes 154Mb of memory, while Skype consumes 68Mb and Miranda 4Mb
My opinion thats unacceptable. Many modern programs consumes large amounts of memory.
Modern program developers don't care about speed and memory optimization,
component writers don't care about speed and memory optimization.
That's bad.
I think that memory consumption must by one of the key parts for programs that stay active on computers all of the time.

[Edited by RoverWhite, September 23]
Just updated to version 6.3 now Viber consumes 193Mb of memory
:(((((((((((((

I used Viber every day for two months then all of a sudden its playing up. Now most of the time when I connect with my partner abroad we get 8 seconds then she goes dead, although she can still hear me!
