Yes, problem still exists with 1.1.48 For example top tells me this laptop is using 33 to 56% of the cpu on btsync. (Using a 9 second average.) I have two directories I'm keeping synced. One directory of 9.6GB in 1196 files across 3 linux mint 15 xfce, 2 windows 7, and 1 ubuntu 10.04. This directory has had no changes in it for hours and is synced. It consists of files that I don't access much. Second directory of 59.9GB in 134117 files. It is only shared between 3 linux mint 15 and one ubuntu 10.04. Everything is synced here but I do change about 30 files a day in this directory. All computers are running the latest 1.1.48 software.
