A question regarding linked list vs vector insert/remove results comparison + Right. I hate it when I hear blanket, categorical assertions like "use lists" or "use arrays". It's a way of putting part of your brain on a vacation/holiday. I let the program itself tell me what's taking the most time, as in this example. |

Why is the main memory for object allocation called the 'heap'? @Robert is right, and don't forget, the folks inventing these terms were just ordinary slobs like us. So what do you call a pile of stuff that has no particular order to it? Well, "heap" is one thing. (I can think of others :) |

Usefulness of pre and post order traversal of binary trees @Kilian: sdg is right. With inorder, you have to be concerned with precedence, unless you put parentheses around everything. |

How to best approach planning and budgeting of software performance optimization efforts? @Paul: And these people are good. It's just the team dynamics and how programmers are taught. I often wish there could be a revolving-door situation between academia and industry, just to keep the profs (I was one) from teaching idiotic stuff (like gprof :) There's tons more wisdom in the pages of stackexchange. |

How to profile a Perl + FastCGi + StarRunner web program? You're right. 20 years ago I worked on a factory-floor system with multiple machines TTY-ing each other. It wasn't easy, but I managed to get time-stamped logs, from which I could trace the history of individual message flows across machines/processes. It wasn't fun, but I did manage to dig out some tumors. Glad you found something that works. |

How to profile a Perl + FastCGi + StarRunner web program? Hi @Paul. This is a case where, in general, my favorite method only takes you part way, because you need visibility into round-trips between server and client, although here's a case where it was effective, even with a protocol in the middle. |

What performance topics should I be aware of? That's my point. A lot of people think that, and they blissfully assume the other 99% is as optimal as it could possibly be. That's the issue. |

What performance topics should I be aware of? You mentioned caching, aliasing, branching, loop unrolling, etc. That's the last 1% of the job. The lion's share is not in things you know ahead of time, it's in things you discover as you work. |
