At least the test suite is not a micro-benchmark. I exercises a large subset of Emacs features, and I don't see anything in these ~110K lines of Elisp that make them significantly different from other Elisp programs. My conclusion is that Emacs is now, on average, about 10% slower.

Your conclusion is premature. While micro-benchmarks don't represent a typical Emacs usage, neither are the tests in the test suite. They are run in batch mode, and the don't involve important Emacs subsystems, such as the display engine.

So the actual slowdown in "normal" usage could be quite different from what the test suite measures.


I think you understood what I meant: bytecode execution in Emacs is now, on average, about 10% slower. Are there other benchmarks (not micro-benchmarks) that could be used to reach what you would consider a mature conclusion?
