I especially love it when people with no knowledge of your code or the systems around it presume to know where the bottlenecks are and tell you to optimize a piece of code nowhere in the vicinity of the critical path. A huge part to optimization is realizing that you have limited time and you want to focus on optimizing the stuff that matters, which means if anyone ever gives you unsolicited advice, they're wrong. Until they've profiled your code, they have no idea where the key optimizations can be found.
