As many of you have experienced, Kontakt 8 seems to cause abnormal save and load times. My Reaper project files take 3 to 5 minutes to save when there are more than a few Kontakt 8 instances loaded, and even longer to load the project initially.
I still have Kontakt 6 full and Kontakt 7 player installed and these issues do not occur with Kontakt 6 or 7, just Kontakt 8. I know other users have commented on experiencing this exact issue as well. Additionally, I recall that Native Instruments developers acknowledged this issue recently as well.
For the meantime, I am stuck using Kontakt 6 and Kontakt 7 player until the issues with Kontakt 8 are resolved. Will the issues be addressed soon? I paid for an upgrade that is completely unusable for me at this point and I am very close to asking for my money back.
