How to reduce scanning time of large synced folder with high latency connection

Hey all,

We're testing FFS for syncing two network shares that have around a 100ms latency. I was hoping that the "use database file to detect changes" would cut down the frequency or eliminate the "scanning" phase of each run, but that doesn't seem to be happening. Scanning 100,000+ files at 5-10 items a second is a bit of a deal-breaker

What's the most sensible way to sync these folders - using RealTimeSync two-way on one of the share hosts seems to do a slow scan of every file every time it runs. Should we instead be running an instance of FFS at each end and pushing in one direction from each host?

Thanks
