If you had bothered to read my post above perhaps it would have saved you some effort.
Faster internet does not necessarily mean faster PEAK Internet. Even if a few users enjoy extremely fast Internet connections, it is POSSIBLE that the AVERAGE for the country or region may be relatively low.
So, a country with faster available PEAK rates conceivably could have lower AVERAGE Internet speed than another country.
Can you understand that?
In fact, per the respected
Akamai report the US AVERAGE Internet speed is only 12.6 Mb/s, which is exceeded by many countries, including many small ones, and some relatively modest ones like the Czech Republic and Romania.
That report does not cover the DR, though.
P.S. I do NOT know whether or not the DR has an average Internet speed higher than the US. I just offered that as a possibility. One reason why the US average is relatively low is the usage of Satellite links. Such links are rarely used by normal users in the DR.
