If you lock table before you insert and unlock it after that. The speed will increase 40% faster than not locking.

    1. ZF doesn’t lock it itself. If you want – you have to do that manually.
    2. The exact improvement is VERY case-specific. No one could say how much would you win (or lose, who knows) if you lock.

    If you don’t experience any performance issues with your application – don’t do that. If you do experience any performance issues – start with profiling and finding the exact reason of your issues.

    PS: that phrase in mysql documentation is very speculative.
