Ok, so you are cleaning my clock :-) I have changed the calcs into a TCF and also matched your logic.
Robert, Could you run the test against your server with the new "workdates3.taf" which calls "daycalc.tcf"? This will be a more accurate time run because it is using the seconds model you used in RB. also included is the seconds logic in just a taf "workdates2.taf" (no tcf call) could you run this time test on your server Ben Johansen - http://www.pcforge.com -Authorized WiTango Reseller http://www.pcforge.com/WitangoGoodies.htm -Authorized Alt-N Reseller http://www.pcforge.com/AltN.htm -----Original Message----- From: Robert Garcia [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 01, 2003 7:03 PM To: [EMAIL PROTECTED] Subject: Re: Witango-Talk: Boosting Server Performance, and TCFs OK, I created an application in RealBasic, and compiled for all platforms. It can be downloaded here: http://public.bighead.net/workdaytest/ I also set up the workday taf on my test server and it can be run here: http://poh.bighead.net/workday/ With the default values, spanning 46020 days my witango v5.1.058 server running on Windows 2000 server, AMD proc. running at 1.5ghz, with 512megs ram, and a 266FSB, it should take 15 seconds. If it takes longer, it is because a couple of you are hitting it at once. Now If I run my RB app on the same machine, it takes about 1/3 of a second if I do not give a progress indication, and about a second if I do. That is even more of a performance increase than I expected. On my mac, the results are about the same, except the progress calc takes just over 2 seconds. Also, I am running my calc within its own thread. If I were to not thread the process, and disable background tasks, I could probably squeeze out another 10% performance. Here is my code from the RB method, you can download the rb project from the link above: Sub calcWDays() dim sDate,eDate,iDate as date dim nDays,wDays,sTicks,eTicks as double dim i as integer dim s as string sTicks = ticks sDate = new date eDate = new date sDate.year = sDateDC.year sDate.month = sDateDC.month sDate.day = sDateDC.day eDate.year = eDateDC.year eDate.month = eDateDC.month eDate.day = eDateDC.day nDays = (eDate.totalSeconds - sDate.totalSeconds)/86400 wDays = 0 iDate = new date iDate = sDate for i = 1 to nDays s = str(iDate.DayOfWeek) if iDate.dayofweek > 1 and iDate.dayofweek < 7 then wDays = wDays + 1 end if iDate.TotalSeconds = iDate.TotalSeconds + 86400 next eTicks = ticks s = "The total number of dates between "+sDate.abbreviatedDate+" and "+eDate.abbreviatedDate+" is "+str(nDays)+". " s = s + "The number of workdays in between is "+str(wDays)+" and the time taken to calculate was "+str((eTicks-sTicks)/60)+" seconds." msgBox s End Sub I tried to make the RB method as Identical to the one in Ben's taf as possible as you can see. sDateDC and eDateDC are the date control objects that the user interacts with.
