Performance goes upwards!

Hi,

with mxgsum=8000 performance strongly decreases (approximately in 2 times for 24 nodes). It was the last job in first series. Probably I should not exceed this value (in decimal) during tuning?
Further I'll do runs as you have suggested, Alex, and then I'll try to vary other tuning options, mentioned above in this discussion.
Thanks for brilliant recommendations, dear Alex! May be, you have still any advice as a reserve :-)?
Thanks to all for various help!
