The problem with reading this in BS thesis form is that it hasn't gone through the wringer enough. Most of the performance comparison results vs C are bogus because (to its credit, as noted), the author accidentally compiled some important support libraries for the C version without optimization and used those on the cluster. Oopsie.

As briefly mentioned in the previous chapter this performance regression might have been caused by the two unoptimized libraries that were compiled on the development laptop and copied to the cluster.
