Memory "optimization" software is basically useless. Windows in fact does a good job of utilizing memory, and there simply is no substitute for having sufficient memory available. Generally optimizers act to supposedly free up memory, and report to you how much extra memory is "free" as they operate. In fact the unused memory is created by calling for a very large memory allocation, which causes Windows to page out what currently occupies memory to the page file on the hard drive, and then immediately releasing the allocated memory so they can show it as being "free". The next time the former memory contents (eg something you're working on) are needed, they have to be re-loaded from the page file, instead of being in memory where they would otherwise have been. And of course the optimizer has to occupy some memory itself, which would otherwise be available to use...
If you are currently getting system lag due to pagefile activity, nothing but more memory will cure that. It may be possible to gain some advantage by ensuring nothing unnecessary is loading at startup, tidying up and defragmenting the hard drive etc.
What specification is your system, especially memory complement, drive size and amount free? How is Virtual Memory set, eg managed by Windows, fixed size page file?
And what specific effect do you experience that's pointing to lack of memory and drive space?
