This relay is rated near the boundary of
minimum Guard rating and goes in and out
of the state.

With a VPS a tremendous number of variables
are at work.  How heavily loaded is the
physical server with other VPS clients?
What kind of NICs are present?  What type
of server, etc?  Is not surprising at all
that the QOS varies wildly.

If you have the ability to use 'tc' instead
of BandwidthRate (per posts earlier this month)
you should do that.  RelayBandwidth* are not
intended for limiting bandwidth in dedicated
relays.  Replace them with BandwidthRate
and BandwidthBurst if you can't use 'tc'.

Per above, huge number of variables easily
explain it.  On top of the variability of the
VPS, the networks could have dramatically
different quality, reachability, loading
and congestion.  You can look at the individual
BWauth ratings for a more complete picture.  Found

The Aruba dedicated Atom server discussed earlier
could make a nice relay, or perhaps the next-up
one for 20 euros.  Perhaps try running the
existing Aruba node as an exit for a month
first to see how they respond.  With
the "reduced" exit policy the worst-case is
a pile of automated complaints about WordPress
brute-force login attacks.  Very minor but
how they respond will be telling.  The exit
policy can be turned off if they freak.

LeaseWeb has 49 euro 100TB servers available
in the Netherlands--killer exit boxes that will
rate high and pull 15000 per Blutmagie.  OVH has
good offerings as well, including the Kimsufi
subsidiary.  Despite 'tor-relays' claims to the
contrary, Kimsufi apparently will tolerate
(at least one) exit nodes:

e_fs_ Kiss208 FR  703 10 6.10 L 443 444 ks3296627.kimsufi.com
e_fsh Kiss208 FR 1503

The above has been an exit for 14 months.
Here's the fastest Kimsufi though this is
probably a Pentium or Xeon:

_gfs_ Unnamed FR  9865 61 6.10 L 443 80 ks26969.kimsufi.com
_gfsh Unnamed FR 10947


But an Aruba exit is perhaps a more diverse
