Looking at
https://atlas.torproject.org/#details/707A9A3358E0D8653089AF32A097570A96400CC6
it has a latency like I would expect and not worse than most users in EU so
latency doesn't seem to really be the problem:

65ms from London
200ms from US west coast
300ms from Japan

Using the same IPs my best relay (at home) with a consensus weight of 62400
and 20MB/s advertised bandwidth has:

5ms from London
120ms from US west coast
220ms from Japan
