Required but not granted http access to 216.34.181.97 slows phpmyadmin down

I use a recently freshly installed phpmyadmin 4.0.5 for the administration of databases on a server with a rather restrictive firewall.

In the firewall logs I see that phpmyadmin tries to open an http connection to the address 216.34.181.97 - which belongs to sourceforge. Probably, this connection is required to look for and display update information.

Now what bothers me is the following:

When I block this connection by the firewall I experience that phpmyadmin does not react for around 1 minute when I directly after a login want to list up all tables of a database. After the "waiting time" everything runs as quickly as expected again.

When I allow for a http connection to 216.34.181.97 the initial slow down of phpmyadmin does not happen. This can be reproduced.

I saw some questions on some internet forums regarding a similar initial slow down of phpmyadmin - but these questions never were answered sufficiently.

So I post some questions here:

Question 1: Is the http connection only for looking for updates ??? Or is there more going on ??

Question 2: Can someone confirm the described behaviour of phpmyadmin?

Question 3: Should this inital automatic trial to get a connection to sourceforge not be handled differently by the phpmyadmin developers in future releases? At least it should not delay user interactions after the login ...

Question 4: Is there a parameter setting by which I can eliminate the trial to connect to sourceforge?

Solution

    1. It's just for version check

    2. Confirmed

    3. There is a parameter to bypass the version check: https://phpmyadmin.readthedocs.org/en/latest/config.html#cfg_VersionCheck

    Also, the version check can be done via a proxy, see https://phpmyadmin.readthedocs.org/en/latest/config.html#cfg_VersionCheckProxyUrl and the parameters that follow.
