Simply put, with that amount of RAM, it won't be easy (if it's even possible at all). Linux will cache items in memory when there's enough available to speed things up, but when another program opens up that requires that memory, the cache will be dumped. Your best bet is to add some RAM to the board. You can usually find it pretty cheap. I'm not sure on the exact specs of the computer, but a 2GB kit (2x1GB sticks) of DDR 3200 goes for just over $20USD on
Amazon. I'd assume the prices would be similar in the Ukraine.
