I have read through the recent posts on slow speeds and WAN and couldn't find a solution to this one. I have a Linux server in US that is syncing to a desktop in South Africa. My old method of transfer is SFTP where I was getting speeds of 440kBs. I am on a 4MB connection this end so that was as good as it gets. Using btsync I see occasional peaks of 100kBs, but mostly it is between 20-60kBs. I have the 2 arrows in the web interface. Listening port open on both machines. I can max connection on torrent traffic on the desktop with a normal torrent client. The files sizes are generally around 20-30MB I just tried with unison the same files and have max speed. Any suggestions?
