Don't underestimate the time required for performance tuning, and be careful to leave yourself learning time, unless you have already extensively used ThreadScope, read GHC Core, and worked with low-level strictness, unpacking, possibly even rewrite rules. I suspect that the measurable performance benefit from lockless data structures might be tricky to tease out of the noise created by unintentional strictness or unboxing issues. And we'd be much happier with one or two really production quality implementations than even six or seven at a student project level. -- Chris Smith
