Defragmentation memory

Myth

It is possible to use programs in view to free and defragment memory (RamBoost, etc).

Reality

FALSE.

Explanations

These programs are supposed to free memory in Windows.
In reality, they are however not efficient and can even slow down the functioning Windows instead of speeding it up.

This myth has a tough life.

Below are some characteristics of the software:

They spend a huge amount of memory and used a lot of ram for windows.
In response, Windows tries to free memory by copying blocks of memory programs background on disk (in pagefile.sys) which is called swap out.

These programs of "defragmentation" appear to release allocated memory.

But in practice

Operation (1) caused disk write.
When you click again on one of the programs in the background, then Windows must return all data in memory (swap in), which again causes disk access very important.

So these programs cause intensive disk access, however forcing Windows to swap blocks of useless memory (instead of letting Windows do it when really necessary).
The disk is thousands of times slower than memory, it causes a global slowdown.

Another danger: The programs that require real-time operation (such as CD recording software) may be disrupted by the swapping of Windows, and therefore you foirer a CD-R or DVD-R.

Finally, memory defragmentation is a myth.
The programs never have access to actual physical memory addresses and always work with virtual addresses.
Only the operating system knows which are physically placed blocks (what memory addresses, or to what disk blocks).
