Why should swap be used as a file copying buffer?
It's RAM replacement, and most file copying only uses ram some blocks at a time, some tens of kb's..

hi...

i was doing a huge copy operation from my hard disk to usb drive and since it was too slow (i found a difference with DSL linux speed(which is known for that) itself in fact ).

i checked my swap space with free command but swap was not at all utilized.

What may be the reason for that?

By the way i have 512 MB ram with celeron 1.7 ghz processor and 1.1 GB of swap space.

Also the data's total size is 4.0 GB.

Is the data one (or a bunch) of big files, or hundreds of little files? DO you have DMA enabled for your harddrive? Are your usb ports 2.0? Is your external drive usb 2.0?
