Why the difference?

[perdomot]

I've got two pcs with gigabit ethernet and a gigabit switch connecting them. When I transfer a 150MB vid file from my main pc to the back up pc, it takes about 4 seconds. When I transfer a folder full of pics of about he same size, it takes around 22 seconds. When I transfer the pic folder from my backup pc to my main pc, it takes 32 seconds. Can someone explain this? Thanks.

Doing just one run of each doesn't matter, to get meaningful stats you have to run multiple tests.

The difference between one file vs a lot is obvious, to copy a file the process (Explorer in this case I assume) has to at least open(), read() and close() the file so if you only do that once it's going to be faster than having to do it a hundred or so times.

it also may be effected buy the read and write speeds of the hard drives. if the read speed of ur backup pc is slower than the read speed of ur main pc, or the write speeds visa virsa, then that can create the difference.
