Hello!!
It seems that Insync uses 50% of CPU or more on idle, starting Insync my system monitor app (Syspeek) shows how the CPU rises and the laptop slows. When I stop the syncing or shut down Insync all goes back to normality. I ran this on a terminal:
pidstat -C insync 10 60 >log
And you can see the results are:

Also, I’ve realized that there isn’t any synchronization at all, the same happens on two different computers.
Very best regards!!
PD: I apologize for my English, it’s not my language. Also, I’m not a power linux user, just a simple user I hope I can explain my self correctly.
