Hi, Thanks to people who send the results of tinyBenchmarks for various CPU, here's the report. What I want to know is whether these results are crap or "normal". It seems that all people succeed in compiling the VM with the source provided. So it may be a candidate for Pharo 1.0 ? The procedure to build the VM was: wget http://lolgzs.free.fr/pharo/squeak-vm/Squeak-3.11.3.2135-pharo-src.tar.gz tar -xvzf Squeak-3.11.3.2135-pharo-src.tar.gz cd Squeak-3.11.3.2135-pharo-src/ mkdir build && cd build ../unix/cmake/configure --CFLAGS="-O2" make The results: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz 64 bits =============================================== 432 M bytecodes/sec; 13 M sends/sec Intel(R) Core(TM)2 Duo CPU T8300 @ 2.40GHz 64 bits =============================================== 424 M bytecodes/sec; 13 M sends/sec Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz 32 bits =============================================== 389 M bytecodes/sec; 10.5 M sends/sec Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz 32 bits =============================================== 330 M bytecodes/sec; 9.2 M sends/sec Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz 64 bits (CFLAGS = -O3) =============================================== 331 M bytecodes/sec; 8.9 M sends/sec Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz 64 bits (CFLAGS = -O2) =============================================== 106 M bytecodes/sec; 3.4 M sends/sec Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz 32 bits =============================================== 220 M bytecodes/sec; 7.6 M sends/sec Intel(R) Pentium(R) 4 CPU 3.00GHz 32 bits =============================================== 93 M bytecodes/sec; 5.5 M sends/sec AMD Athlon(tm) 64 Processor 3000+ =============================================== 87 M bytecodes/sec; 4.5 M sends/sec Laurent Laffont
