Assume : Computer A : Memory Chip Sizes : ( 2 GB , 1 GB , 2 GB , 1 GB ) : Working SLOW . FreeBSD A Computer B : Memory Chip Sizes : ( 2 GB , 2 GB , 2 GB , 2 GB ) : Working FAST . FreeBSD B Interchange memory chips : Computer A : Memory Chip Sizes : ( 2 GB , 2 GB , 2 GB , 2 GB ) : Working FAST . FreeBSD A Computer B : Memory Chip Sizes : ( 2 GB , 1 GB , 2 GB , 1 GB ) : Working SLOW . FreeBSD B Then : Interchanging only memory chips is interchanging also the SPEED . Means : FreeBSD installation is NOT important ( or effective ) . Thank you very much . Mehmet Erol Sanliturk
