hmmm......goto wins, but why is your system only doing less than a million loops per second? The slowest I got on my PC was 13 million loops per second, and the fastest was 15.3 MLPS.
Also, do you have users actually processing? My system is for me only and therefore is more consistent when testing speed. I agree that the speed really doesn't matter a whole lot. In 10 years we'll all be laughing at how slow our systems were in 2004. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Monday, December 13, 2004 11:32 To: [EMAIL PROTECTED] Subject: RE: [U2] LOOP or GOTO on READNEXT Allen E.

Using UniData 6.0 on AIX 5.1 I tested a similar program with a tighter GOTO loop: 01: * Test Loop Speeds 02: * 03: CTR = 0 04: ETIME = TIME() + 5 05: LOOP WHILE TIME() < ETIME DO 06: CTR += 1 07: REPEAT 08: PRINT "While ":CTR 09: * 10: CTR = 0 11: ETIME = TIME() + 5 12: 10 CTR += 1 13: IF TIME() < ETIME THEN GOTO 10 14: PRINT "Go To ":CTR I also wrote a separate program with lines 2-9 above after line 14, so I could test if the order of execution made a difference. I ran each program four times, with the following results ("W" indicates "Winner" :->) ------ Go To First ----- ------ While First ----- Go To Count While Count Go To Count While Count ----------- ----------- ----------- ----------- 769730 W 752380 667050 W 458545 655809 734709 W 747373 W 592827 576565 688953 W 785676 W 611628 629807 748265 W 714679 W 564908 The second loop for whatever reason seems to have an advantage. Overall, I suspect there isn't a lot of difference. --Tom Pellitieri Century Equipment ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
