Do you guys feel "Isolate" command in the rhino 8 SR13 is a bit slower

I’ve compared the same model with rhino 6 SR35 and rhino 8 SR13, the rhino 8 is much slower

Just add something by my personal account.
These two gif show that in rhino 6 isolate command works very quickly but very slow in rhino 8. Same model with the latest software.
rhino 6
rhino 8

Hi Roy -

Could you upload that model from this page so that we can try to reproduce the difference between Rhino 6 and Rhino 8? Please add a link to this topic in the comments field on that page.
