It's just pure curiosity if the Sknote code improved in terms of CPU cycles (doesn't look like it currently). And to be honest, GTS-39 was also rumored to be improved in terms of CPU load throughout the years, and it never really happened. Would be surprising if the load is suddenly cut in half with more recent plugin versions.
It's not like that there are technical comrpessors or similar compressor concepts on the market with only a fraction of the load (and a demo without jumping hoops). So yeah...
