Hello ,

let's say , I'm moving large files through network between devices
what is the fastest way to do this ?
what i came up with :-

1) using regular file operations with an in memory limit of 4MB which
when filled written to disk and re-filled again

2) using memory mapped files in the following way , map first 20MB of
file and after finishing them flush and map next 20MB
which of them should be faster in writting to disk ? and less memory consuming

or is there faster ways ?
