Benchmarking is difficult, and most benchmarks are easily 'oriented'.
(pure) Python is slower than Java for some tasks, and as fast as C for
some others. In the first case, it's quite possible that a C-based

If you go that way, Java is way slower than C++ - and let's not talk

If you have very large datasets, you're probably using a serious RDBMS,
that will do most of the job.

Pretty good - but I wouldn't call MySQL a serious RDBMS.

If your GUI is complex and important enough to need a GUI builder (which
I guess is what you mean by IDE), then forget about Tkinter, and go for
either pyGTK, pyQT or wxPython.

HTTP is language-agnostic.
