I have a Dell Inspiron 1520 with 2 GB of RAM and a 500 GB hard drive that has 2 NTFS partitions for windows and a 44 GB FAT32 partition (sda3) from which I run Knoppix 7.0.4 (fromhd=/dev/sda3) with a 4GB persistent image. I boot from a 256 MB USB stick that I created with UNetbootin from the bootonly iso.

My question is this. Since available RAM has not been a problem, is there any value in creating a swap file on sda3 using mkdosswap? If so, how big should it be and should I anticipate any problems?
