- bytecode results Chris Gray
As some of the folks who have been on the list for a while may remember, I've
been messing around with a bytecode engine for my MUD. It already has a
parse-tree interpreter, but I wanted to see if I could squeeze more speed
out of it. Also, its been great fun doing it. Anyway, I've now finished
off the X86 version of the bytecode engine, and thought I would report
the results here in case someone else is thinking of doing something like
this. Everything is straight ANSI C code, except that I've used gcc's
language extension of label variables. Here is a cut from one of my
documentation files I've just updated:
The final results for this machine (300 Mhz P-II running Linux) are (the
test program in this case is 100 iterations of the 256x256 fractal terrain
generation, done in a very straightforward way):
Unoptimized MUD server:
tree interpreter: 187 seconds
bytecode machine: 77 seconds
Optimized MUD server:
tree interpreter: 93 seconds
bytecode machine: 31 seconds
Native code:
unoptimized: 4 seconds
optimized: 2 seconds
So, in this case, the bytecode machine is about 15 times slower than
native execution and only about 3 times faster than the tree interpreter,
fitting in with the conjectures above.
Repeating the original "Towers of Hanoi" experiment:
Unoptimized MUD server:
tree interpreter: n = 22: 57 n = 23: 114
bytecode machine: n = 22: 14 n = 23: 29
Optimized MUD server:
tree interpreter: n = 22: 34 n = 23: 68
bytecode machine: n = 22: 4 n = 23: 9
Native code:
unoptimized: n = 22: 0.53 n = 23: 1.08
optimized: n = 22: 0.68 n = 23: 1.40
The native code times are wierd. Proper optimization flags to gcc (I just
used '-O') should get better optimized times than unoptimized. With this
example, bytecode is 4 - 8 times faster than the tree interpreter, and
7 - 8 times slower than native code.

Don't design inefficiency in - it'll happen in the implementation.
