Comment This illustrates why PhD's shouldn't be in busines (Score 1) 486
Of course, there are exceptions. But many PhD's I've known make lousy programmers, in terms of producing good software.
I've come to think that the skills needed to be a good post-graduate student are different from the skills needed to be a good professional developer.
Professional developers know (or should know) how to optimize code, when necessary. All else being equal, optimized code will ALWAYS be faster in memory than on disk. The two examples in this research are NOT equal. A more equal test would be to output to a memory stream, vs. a file stream. I'll bet the results would be quite different.
