We have been using Sync and Sync Pro on several machines, and use this to distribute copies of our main shared files. We have a qnap nas that takes about 3-5 mins to show the complete UI, and working on any listing is painfully slow in terms of UI response. I thought this was restricted to NAS issues with only 2gb memory on board, but recently we added a 32gb memory modern server with a 'sync' account in my private cloud, and the UI is just as bad. Admittedly we have about 5 folders that are rather large (30gb) and have many sub folders, but to see the UI become unresponsive for about 4 seconds, then recover only to be very slow at responding makes maintenance almost impossible. Is this a memory management problem in the UI? Are there any tweaks I could use to improve responsiveness? Can Sync be run effectively as a 'service'? Would this be better performance-wise? This spoils an otherwise brilliant product for me.
