Mine is currently 448Kb/s, however I only have unlimited bandwidth at weekends and between 12am - 8am weedays. Between 8am - 12am te ISP sets a cap of 50GB for the month, with overuse charged at £0.50 per GB after that, so I throttle the upload speed during these peek time hours to 15KB/s, which slows things down.

Switching to the ISP Be* will sort that issue out as they don't have any caps.
