Script & Hotkey Performance

Scripts are semi-compiled while they're being loaded and syntax-checked. In addition to reducing the memory consumed by the script, this process also enhances runtime performance (by orders of magnitude in some cases). The performance boost is greatest when SetBatchLines is -1, meaning that the script is running at maximum speed.

In addition to SetBatchLines, the following commands may also affect performance depending on the nature of the script: SetKeyDelay, SetMouseDelay, SetWinDelay, SetControlDelay, and SetDefaultMouseSpeed.

Here are the technical details of the semi-compiling process:
