Following loop shows worse performance of Origin8.5.1 compared to Origin7.5 on the same WinXP operating system. The benchmark requires a worksheet Data1 with row numbers 1 to 80 in the second column. sec; K=0; Loop(j,1,20000) { K+=1; col(2)+=1; }; K=; sec -e time; type (Elapsed time = $(time) sec.); Origin7.5: Elapsed time = 0.968 sec. Origin8.5.1 : Elapsed time = 1.531 sec. which is 58% slower. Any explanation for it?
