Your a noobie and you already have 6 machines? Damn! Nice work.
Anyways. The answer to your question regarding slow saves on the web configuration page is normal.
But a save shouldn't be more than 30 seconds at the most. Make sure you close out of all unused applications
running in the background, that may help.
Run an internet speedtest at
www.Speedtest.NetIs your internet bandwith low? If so, then its possible that your
6 existing Antminers are taking a chunk of your internet speed.
If you have other things running off your router, such as other computers
they may also be slowing your internet speed down.
Bottom line, run a speedtest. Let us know what the results are.
