Well, just to post my experience. Using native with gig performer as a host, it tales maybe 1 and half second to open the gui of native, maybe closing it as a little faster. My laptop has a i5 gen 10 u series so is not particularly powerful but works fine. But i can relate that native has become more and more buggy, and i think (just my opinion) that there are bugs that only happens in Macs while there are others happening in windows. For example the midi crashing native on the vst 3 version still happens to me even on the latest version. Vst does not have that issue when i use the FBV MKII to change patches. So, probably the solution will be to wait untile line 6 fix this or maybe with any upcoming helix mkii if it happens any time soon
