Slow transfers Question/Problem:
I am getting poor transfer rates when I use WS_FTP Pro to transfer my files. Is there anything I can do?
Product: WS_FTP Professional, WS_FTP Home
Version: All
Platform: All supported OS
Answer/Solution:
The transfer rate of files/information is determined by several factors:
the type of internet connection
the traffic on the internet
the traffic on the server
the network traffic on the ISP that is hosting the connection.
These variables are outside of the control of the WS_FTP program itself. If you are dissatisfied with the transfer rate you are getting, you might want to change the type of internet connection you are using. You can test your connection speed at this web site:
