User controlled i/o block size?
...The end result is I'm only using 50% of the available bandwidth.
Not that I'm copying my source folder tree to a newly created folder
tree, so there is not any reading of the destination needed.
My ultimate would be something like:
while (files) {
while (data_in_file) {
read user_defined_blocksize to ram from file
write user_defined_blocksize from ram to file
}
fsync() ensure 1.5 GB file is on disk
} endwhile
Thanks
