Playmo must work by providing a DNS service which arranges to route at least some traffic via their own servers. This will give access to certain foreign sites that are otherwise not available, but may also slow down some other sites. It could even interfere with the data from other sites; I am not suggesting that Playmo does this, just pointing out that they could.
To find the fastest reliable alternatives to the BE servers, try DNSBench. http://www.grc.com/dns/benchmark.htm
. You can add BE servers and Playmo ones to the default DNSBench list to see how they compare with some of the best public servers. DNSBench will also point out some name servers that interfere with the standard name resolution; though it can't judge whether such interference is for good or for bad reasons, and it doesn't notice all such interference (eg it does flag that Playmo interferes with the resolution for netflix.com). Playmo dns servers seem to be ok, but not close to the fastest.
I'm not trying to put you off Playmo, just warning of extra things you may want to look into for using them.
Moved (with trepidation) to BT Infinity 2 for upload speed. Happy BE user for several years.
