Openworld make Peer to Peer appear Slowworld
Users of the Openworld broadband service have variously complained about peer 2 peer application speeds in the last few weeks, mainly affecting Kazza, Gnutella and EDonkey.An enterprising Software Developer Mark Hutton who is using the BTO Home 500 service has run some tests sending just data between two machines on the various ports that the sharing programs use, a summary of the results follows:
| Napster | Port 6699 | 58.1KB/sec |
| Gnutella | Port 6346 | 3.75KB/sec |
| Edonkey | Port 4662 | 1.5KB/sec |
| Kazza | 2.8KB/sec | |
| Test | (Kazza port+1) | 58.1KB/sec |
It does very much look like some form of throttling intentional or otherwise is occurring on traffic through BTopenworld. Perhaps BTopenworld are running a maximum bandwidth per port policy, and restricting some ports to ensure that any single application does not overwhelm the network - there is no documentation to suggest this or any feedback to users from the helpdesk.
