Memory throughput:
This test checks your memory subsystems speed. The value it shows is the average throughput for arrays from 512 Kbytes to 32 Mbytes size. You should run this test several times to ensure that there is enough free memory available. The first two or three times you’re running it most systems are swapping which reduces drastically the performance.
Attention: If you’re running CliBench with multiple threads you must be aware, that each thread consumes 32 MB of RAM. So do not run more than 2 threads on a 64 MB machine, or you’re system will probably crash
