Why are non packed records faster? The difference occurs at memory allocation or at memory access?
In addition to what the others said, think of it like your 32 bit processor suddenly being a 8 bit processor: it has to manually load 4 times 8 bit, arrange them into a 32 bit value, and only then use it. With non packed, it can use the value directly.
