I'll also cover techniques that are purported to speed up Visual Basic code, but don't, or at least not as much as claimed. TrueTime is perfect for showing off how Visual Basic performs and even how it works under the hood. The true view Throughout this paper you'll find screen shots of TrueTime showing source code. To the left of each line of source are several columns of additional information about that line. Count is the number of times that line of code executed during a run of the program.
Functions is the number of function calls that executed as a result of that line of source code.
TrueTime has other statistics for source code, but these three are the most useful. The Count column makes it easy to spot code that executes frequently, so you know that even small performance improvements there will have a substantial impact on overall performance. Functions shows you when a line of source code is making numerous function calls and might benefit from some simplification. That makes it easier to see compare the results of different approaches. Percentages, though, are easier to see, comprehend, and compare.
