Box seems to have abandoned any effort to improve sync. It has the same problems that it had 5? 6? 7? years ago. It takes forever to sync. It consumes huge amounts of CPU. It gets hung up all the time. A former associate who was friends with an employee of Box once (about 5 years ago) complained to the friend about the problems with sync. The employee's response: "use sync less." That appears to be Box's strategy: they don't fix the problems with the program; rather, their advice is use the program less. That's pathetic. Fix your software.
