Development #42

Keep repaint (appearance) and reflow (layout) to a minimum

A repaint is a change in appearance of a DOM (Document Object Model) element, while a reflow is a change/recalculation of the position of the elements in the DOM. You should avoid triggering these two operations as they are resource-expensive, especially in terms of CPU usage.

Development #64

Cache the bytecode

Bytecode (called opcode for PHP) is the binary code generated from the source code. Some accelerators are able to cache bytecode, which avoids needing to recompile it from the source code every time. Less time spent compiling equals less CPU and RAM used.
