Slow "create new project from existing files"

I have large project on remote server.

Full sync it by rsync get <1minute...

Full sync it by "create new project from existing files" in phpstorm get >1hour. Why? If you download module so slowly - may be best solution to use another popular tools i.e. rsync?

P.S. it not problem of perfomance local machine. i use top i7, 32gb ram and nvme ssd. It is problem in download module of phpstorm and non-optimal algoritm
