| |
I've made some tests to load a computer (1GB memory). A litle process starts eating 900 MB then slowly eats the remainder of the memory 1MB by 1MB and does a "data shake": 200,000 times a memcpy of 4000 bytes randomly choosen.
I want to test the swap capability.
Solaris was used under XWindow, Linux under text console... What do I forget to comfigure or tune? Don't let me with such bad values.......
