Why is this new Mac so slow?

Up until just recently I had been running an older version of illustrator (cc 2017) on a mid 2014 MacBook Pro (2.8GHz Intel Core i7 with 16 gigs of ram, a 1 TB drive, running 10.10.6) It was a workhorse and I frequently pushed very large complex files in illustrator and photoshop. It was no slouch but I decided I would update hardware... thinking it would be faster and make me more efficient.

Last week I proudly purchased my brand new MacBook Pro. It's arguably the fastest MacBook Pro made with the fastest processor and as much ram as possible. (2.9 GHz Intel Core i9 with 32 gigs of ram and 2 TB hard drive running 10.14.2)

Disappointingly this new setup seems sluggish by comparison to my old one in both photoshop and illustrator. Things like simple copy paste and move, nudge, etc... things are an annoying tick behind what I've been used to in my previous old school, out-of-date setup.

So are there any suggestions for hot-rodding this thing up? Like what are the ideal memory allotments, and tricks.  BTW - I have a 6 TB external drive that I'm running as scratch disk with about 3TB open.
