@Helen, Oh, sorry, I gave the wrong code. This one is right: https://link.getsync.com/#f=Kindle伴侣精品书库&sz=15E8&t=2&s=THQ42ZMMYPIV4TLU22VAIIJ5KPWDGYA6TDOUOKMQN34GIMVI6JGQ&i=CVPMU4DJI2SYBVMAJ4DEO4LQMTP75JT7H&v=2.3

@Helen，15+GB，about 3000 files, about 20 users. I have set Selective Sync On. Usually, it takes 1-2 seconds to give me a response after I touched the screen(at best), or more than 5 seconds( at worst). It is public, if you want to try( B4TDKK7OLYBW7OAG3ILYLQPLFK3QSTAS4 ). By the way, I also have other directories. They may have some influence, but not as much at this one. My device: iPhone6s, iOS9.3.3 Beta2

I am using sync on my iPhone. It works well at most of time. But when I try to connect to a directory which contains lots of files, the APP gets very slow. It takes very long time to give a response to my action. And after I disconnect that directory, everything gets well. Is it related with the rescan interval ? Please fix this issue. Thanks!
