  QUIC was recently standardized as RFC 9000, but the performance of QUIC over
geostationary satellite links is problematic due to the non-applicability of
Performance Enhancing Proxies. As of today, there are more than a dozen of
different QUIC implementations. So far performance evaluations of QUIC over
satellite links were limited to specific QUIC implementations. By deploying a
modified version of the IETF QUIC-Interop-Runner, this paper evaluates the
performance of multiple QUIC implementations over multiple geostationary
satellite links. This includes two emulated ones (with and without packet loss)
and two real ones. The results show that the goodput achieved with QUIC over
geostationary satellite links is very poor in general, and especially poor when
there is packet loss. Some implementations fail completely and the performance
of the other implementations varies greatly. The performance depends on both
client and server implementation.
