1Mbit/s should be enough. Not good but not bad.

There is no  Requirement for bandwidth that I'm aware of.  Studio uses ODBC to connect to the Server, and it will have to bring over the class/routine list in order for the open dialog to work, and if you have a large system this can take some time.  I think as long as Studio is getting information, though, that it should work (albeit slowly).  If you find Studio is working too slowly, you can import your project to a local instance and work off of that. 

I think latency is more important than bandwith. Studio works fine on 100kb/s wireless connection, but when ping goes higher than 1s it becomes kind of slow.

Correct, bandwidth is not so much of an issue. Latency can be an issue as a high latency will make all actions that require server interaction be perceived slowly.

Also, you should be aware that Studio runs a server status check on a regular basis by default. If your latency or connection is bad you should increase the timeouts, otherwise, you will see a popup asking for a reconnection pretty often. The setting can be found here: Tools->Options, go to Environment->Advanced and take a look at the "Enable server status check" setting.

Is anybody knows why Studio in Windows7 through Parallels which connected to server on the host, too often says  that  connection have been lost, and offers to restart Studio? Version used on both sides 2016.1.

Dmitry - Have you tried Studio through VMware Fusion? Fusion seems to be more stable for me than Parallels.

No, I've already bought Parallels. I thought that Parallels, much better in some cases then Fusion. And I don't even know how to localize this problem, because after restarting studio, it seems like everithing works well, but sometime  when it happens when I edited some file, and studio locked it, then I need to kill previous Studio's job.
