Performance problem

Hi Knack Team,
We are still having huge performance issues.
Please go here:
Please try to open settings of second column, the one with empty name.
To open the settings I need to wait ~4-5 minutes, not to mention setup or save.
This doesn't work.
Please advice.
Network on browser:
6 minutes to open column setup :/
oh and one more thing I have 200mb/s connectivity to the net, so this is not a problem
Network from browser:
that's one that took almost 3 min to load :/
