Hello,
I had some suspicous for a while but we did a little test with a
computer that dual boot Windows XP and (Ubuntu) Linux to run
tinyBenchmarks. (The computer happens to be a 1.8GHz Pentium-M Dell
laptop.)
On Windows, 3.10.6 VM (pre-compiled one on the site) with
etoys-dev.image, the result was:
311 million bytecodes/sec, 8.9 million sends/sec
On Linux, 3.9-8 VM (pre-compiled one on the site) with etoys-dev.image
the result was:
190 million bytecodes/ec, 5.7 million seonds/sec
Has any of you been experiencing similar gap? Have anybody looked
at the generated code, or has anybody done some experiment recently?
