CUSTOMERS  Here is a little comparison between RamBooster and 
3 similar, but commercial programs. 

Values while program sits in the tray doing nothing but 
running in the background.

Read with care and think about this the program(XXXTurbo) that costs 
almost 1½ times as much as the cheapest (Win-Ram-Booster) demands 5 times more memory and takes 6.5 - 6 % more cpu. 
(Win-Ram-Booster has nothing to do with my 
original RamBooster. The author chose the same name 
by accident, and continued to use it, because I had 
nothing against it) 

This comparison is supposed to be neutral and always remember that 
my program might seem to be the best  BUT this is only 1 chart 
and not the whole truth.
These things are difficult but remember this:
"Most people think, that you can tell the RAM usage of a program just by the size of it's executable. THAT's ABSOLUTELY WRONG !!! See XXXTurbo: The exe file 
is only 512 KB big, but all in all it uses nearly 10 MB
(that's incredible, isn't it?) 
This program does waste more RAM than it gives you back..." 
(An e-mail from a person who used to use XXXTurbo) 

That chart is mainly made to help you to compare the features 
of this kind of programs in case you decide to buy one. 

You should also remember that RamBooster is freeware and 
I may decide to stop updating it anytime, and after that there is no 
support anymore. If you buy a good commercial program from 
a company that has other products also, not only 1 memory optimizer, 
you can be 100% sure you are not left alone if you have problems. 

Noticeable is that Win-RamBooster has been updated very often, and 
the program gets better and better all the time, but the makers of XXXTurbo don't seem to care about the program.
I have not seen any updates 
to XXXMemPro either. So my guess is that if you want good 
commercial product support and updates, buy Win-RamBooster.
But, why? you can get the best here FREE!

The program used to monitor these values is TaskInfo 98
by Igor Arsenin 
and you can find it HERE
Worth downloading, it is an excellent program. 
Also other programs were used to monitor the values.
