Yes.
Let's assume I set the record to packed 16bytes, this would make
reading and writing records as a whole safe on all platform/
architecture
combinations right? Apart from a few padding bytes, what are the
performance penalties of doing this then? Why would there be
penalties?
The cpu cache will contain lots of unused padding bytes.
