As another commented posted elsewhere, GC is all about tradeoffs, and for a govern set of GC tradeoffs there will always be pathological cases. Another GC might work out of the box for this workload, but perform very badly for a workload at which Go's GC excels. As others have already mentioned, the fact that he was so easily able to tune the GC is a testament to Go's simplicity.

There are lots of good criticisms of Go to be had, but it's runtime is pretty remarkable, in my opinion.
