Hi
These numbers are not enough to effect system performance. Z reports can take too long to execute because of their logic but standard functionality shouldn't take this much long. Did you check the note and other related notes in it? I hope you'd overcome this issue by implementing this note or some other according to your scenario which you can see in related notes in the one I have shared. \
I don't think so it is related to server profile parameters but since I am SD guy not a BASIS one so some BASIS guy could comment on this better than me.
Thank$
