Regarding error handling, I agree with this author[0], and find the C-based approach much better than C++'s try/throw/catch methods. Regarding execution times, I don't know from first-hand experience, I did some research and found this[1]. The third sentence in that reply ("The error code is not sensitive to the percentage of occurrence") is AFAIK wrong (because of speculative execution, I believe?), but the rest seems quite solid.
