BUG: 3.0 WAIT WINDOW Display Performance Much Slower than 2.6

MORE INFORMATION

The following table illustrates the times to completion for the following code loops, all run on a Power Macintosh 9500/132. Each loop cycles 1000 times, with each pass displaying a string up to 9 characters in length:

    Loop           Product                         Time
    -------------- ------------------------------- --------
    WAIT WINDOW    Visual FoxPro 3.0 Power Mac      31.4
    WAIT WINDOW    FoxPro 2.6 Power Mac              3.1
    SET MESSAGE    Visual FoxPro 3.0                 4.2
    SET MESSAGE    FoxPro 2.6 Power Mac              3.3
				

NOTE: With different hardware or shorter string lengths, the disparity in display speed between these two methods may not be as dramatic.

Sample Code

   * WAIT WINDOW
   nStart = SECONDS()
   FOR x = 1 to 1000
     WAIT WINDOW REPLICATE( 'X', MOD( x, 10))  NOWAIT && cycling string
   ENDFOR
   ? "Time in seconds to run 1000 WAIT WINDOWs: "
   ?? SECONDS() - nStart

   * SET MESSAGE
   nStart = SECONDS()
   FOR x = 1 to 1000
     SET MESSAGE TO REPLICATE( 'X', MOD( x, 10))  && cycling string
   ENDFOR
   ? "Time in seconds to run 1000 SET MESSAGEs: "
   ?? SECONDS() - nStart
