+Using profilers is a ***must*** to get accurate pictures of your performance woes.
+
+While trusting your (hopefully sharply honed :wink:) programming wisdom is a good-ish thing,
+it can only get you so far before *actively hindering you*...
+so acquiring more knowledge via profiling is your best bet.

+Thankfully, most common <abbr title="Integrated Development Environments">IDEs</abbr>
+(such as Microsoft's Visual Studio, various JetBrains products, the Eclipse family, etc.)
+have profilers, or integrations with them, built right into them, making profiling your software relatively straight forward...
+
+Of course, learning how to use and interpret the data a profiler outputs is a whole 'nother topic,
+on which entire books have been written, so we won't get into that here.
