Still having this problem. BT Sync version 1.2.82 The two systems are identical Xeon Quadcore systems (PowerEdge T110) Gigabit networking (gig cisco switch), Cat 6 wiring. Shows arrows (not cloud) I'm getting 400KB/s - 1.4MB/s. Occasionally It'll hit 2MB/s These systems have almost no load on them (0-5%) I get close to 100MB/s when copying with ROBOCOPY between these systems. ugh.
