I'm looking for input from my fellow monks who have undertaken large project using perl. At this point, I'm working on a project which is a plug-in program of sorts (the main program only contains ~100 lines of code) the basis of the program is in the Modules it uses. At the moment, I'm looking at a minimum of 15 - 20 database calls per instruction and roughly 40 - 50k lines of code. At the end I expect it to reach somewhere between 300 - 500k lines of code (just a guess based on percentages), now... Based on your past experiences could those enlightened ones fill me in as to what I should expect as far as performance hits using perl? What is the largest project you've undertaken using perl and what sorts of methods have you used to increase performance?
