How much difference is between 1.0 GB ram and 4.0 GB of ram?
First, four gigabytes of memory is more than one gigabyte. Four
gigabytes is also the maximum amount of memory a non-PAE 32-bit
computer can handle, but most modern systems now support PAE.
Having more memory on your computer can also improve performance by
minimizing the amount of page swaps needed to your pagefile or swap
partition.
