title: Libtorrent- Keep the whole data in cache and flush later
body: <p>I am using libtorrent to transfer data to 10k+ nodes. Here the data I am transferring is very small in size(size of 10-50 mb). I want all the nodes to keep data in memory until all the other nodes finish downloading to avoid more disk io usage, and then flush the data to disk when the download is complete in all the host. Is there any way to do that ?</p>
