It takes a little long time to get the root project.

It may happen when you perform Get for the first time. The time depends on the project size, network bandwidth/stability, hardware configuration, and etc. It will be much faster when you get the files for the second time, there is cache in local.

Also, SourceAnywhere Standalone supports delta transfer. It can be enabled by checking the Use Delta transfer for data transfer in SourceAnywhere Standalone Client menu Tools->Options->General tab.
