Elevator Pitch Can Perl possibly be faster? YES! How to improve the performance of your Perl scripts using mostly minor changes to your code. Performance often comes at a cost–more memory! So we’ll also look at techniques to shrink your Perl script/module footprint.
Description This is a followup to my “Perl Optimization Tidbits” talk in 2018. Then we looked at many minor performance differences in expressions like ++$x vs. $x++, “abc” vs. ‘abc’, etc. We go into more depth with more comparisons, but also cover larger strategies–algorithmic, structural, and other optimization techniques to get the best performance. In addition we’ll look at various ways of profiling your code so you can see where your slow places are. Some of these techniques and strategies can be applied to improving performance of other languages as well.
