Another great article. Most of it I have to take in at a high level due my limited knowledge. I would guess the Suduko test involves heavy recursion/backtracing to compare memory allocation/de-allocation times of heap-dynamic arrays (C#) verses stack-dynamic arrays (C++)? Anyway, I'll bookmark this one for re-read in few months. In the meantime, I'll throw his gc quote on the pile as this guy seems an expert to me.
"Memory management concerns (not benchmarked here) are different in C# than C++. In particular, C# memory allocations are extremely fast, but the garbage collector is a wildcard: it may be fast or slow depending on your memory allocation patterns. And Microsoft has not provided any good way to measure GC performance. There are various guidelines to optimize GC: let objects die young where possible, avoid thick pointer trees (e.g. linked lists or SortedDictionary, a red-black tree), and so on; but it's really outside the scope of this article."
