Performance Tuning of a large Method

From: Craig S.
Sent on: Tuesday, October 23, 2012 9:46 AM
Good morning,

I'm working on a rather high trafficked ecommerce platform at the moment where I seem to having some performance issues.

I've hooked visualJVM up to the application to find that one particular method is taking over 40 seconds to complete when load is high. Looking at the method, I see it's a 185 line copy and paste job from a legacy codebase that has some rather verbose conditionals and lots of interactions with Collections.

I know I haven't given enough information for anyone to really help me but I'm curious as to how you would generally go about dealing with a 185 line, synchronised java method that was lifted out of a legacy codebase. Where am I supposed to begin when refactoring this mess?

Craig
