Not entirely true. Go is a general purpose language, it is a
successor to C as envisioned by Rob Pike, Russ Cox, and others
(I am not sure how much input Brian Kernighan has had).
However, because of current traction in Web servers and general
networking, it is clear that that is where the bulk of the
libraries are. Canonical also use it for Qt UI applications. I
am not sure of Google real intent for Go on Android, but there
is one.

They also saw a 100% increase in performance when it was
rewritten, and a 20% fall with this latest rewrite. I
anticipate great improvement for the 1.6 rewrite. I am
surprised they are retaining having only a single garbage
collector: different usages generally require different garbage
collection strategies. Having said that Java is moving from
having four collectors, to having one, it is going to be
interesting to see if G1 meets the needs of all JVM usages.

Until some organization properly funds a suite of garbage
collectors for different performance targets, you have what
there is.
The performance decrease has been there since 1.4 and there is no
way to remove it - write barriers are the cost you pay for
concurrent collection. Go was already much slower than other
compiled languages, now it probably struggles to keep up with
mono.
