Hi Slávek,

I just ran git clone https://mirror.git.trinitydesktop.org/cgit/tde for
a few minutes on three VPSs in data centers in Texas, California, and
Washington State.  In each case there was a high initial transfer rate
around 35Mbps.  After less than a minute transfer rate dropped drastically
or even zeroed before bouncing around and finally settling near 200kbps.

When I tested transfers from Washington State to Texas I was able to
sustain around 47Mbps.  Transfers from the TDE UK mirror to Texas started
around 170Mbps before bouncing around wildly but averaged 90Mbps over
several minutes. 

I doubt this is an artifact of disk caching.  I suspect something is
limiting mirror.git.trinitydesktop.org bandwidth despite the 300Mbps
connection.
