I wonder how stable the measurements are. I've just upgraded this
ARMini to RO 5.22 so have redone the measurements, still with NS#2771:
161126 bytes/second. That's a massive increase. I had visited a
number of websites for that.

Trying going to just www.buxtonweather.co.uk (my homepage) as before
now gives 154588 bytes/second - only 4% different.

Have I missed something, or have ROOL done something spectacular in
the changes from 5.20 to 5.22?
