Question A quesstion about stream aligned.

I am confused about stream aligned, but I did not find any information related to it.
Why writing bits that do fill the whole byte, or when writing bools as they are written as bits, performance is decreased for each write and read.?
If anyone can help me answer my doubts, I would be very grateful.

If your stream is unaligned (lets say you wrote 3 bits already) and then you write something like a ulong (8 bytes) this ulong will not just be written into a single memory location but instead 7 bytes and 5 bits will be written into the first location and the remaining 3 bits into the next one. This can be much slower because the CPU needs to perform more than twice the operations.

 

Thanks for your answer!
