Sounds like issues with Anti-malware virus programs. 
The ones that insert themselves into your tcp/ip data stream to examine all of your traffic so that you don't' download "bad stuff."

I had to shut off thtat processing in Sophos because it had gotten so bad (i.e. taking FOREVER to load any program that talked to the internet.)

That was a "sudden" change in how Sophos was working. At first I thought it was  simply because I had turned on the iCloud drive (which does impact things).
But after a lot of trial and no-luck turned off the option in Sophos.

Long ago I had tried Avast! and discovered that it's anti-malware was simply horrible in what it did to a Mac.
