Compare it to some other older DAWs like Logic or DP that I use and it rarely glitches when adding a soft synth etc. that Live does for it's usually smooth operations under task. I used to relate it to the warping, real time polling of pretty much everything etc. Live and it's stepchild Bitwig are both heavy CPU users.
I don't have any real answers as to why this is happening for you guys, but in the bigger picture Live has always been a huge resource hog.
