SPARC 2 (40 MHz, 40 MB RAM) -- running X and KDE - Solaris 7 Pystone(1.1) time for 10000 passes = 40.48 This machine benchmarks at 247.036 pystones/second Ultra 5 (166 MHz (?), 128 MB RAM) -- running X and KDE- Solaris 7 Pystone(1.1) time for 10000 passes = 3.03 This machine benchmarks at 3300.33 pystones/second Enterprise 450 (2x266 MHz (?), 1024 MB RAM) -- running many, many services (only 3 users) - Solaris 7 Pystone(1.1) time for 10000 passes = 2.03 This machine benchmarks at 4926.11 pystones/second Gateway Pentium III (450 MHz, 128MB RAM) -- running X and Zope - Red Hat 6.0 Pystone(1.1) time for 10000 passes = 1.86 This machine benchmarks at 5376.34 pystones/second Pentium I (100MHz, 40MB RAM) -- running Zope - Red Hat 5.2 Pystone(1.1) time for 10000 passes = 27.82 This machine benchmarks at 359.454 pystones/second Note that these machines are not optimized and run a lot of useless services. I did these tests while I was writing the e-mail. I do not think that Python is so much slower in Solaris, but UNIX runs so many more processes that a comparison is not at the right place. You need someone to optimize the machine only for this test, namely kill all services and minimize the kernel (optimizations I usually do not care about so much). regards, stephan -- Stephan Richter iXL - Software Designer and Engineer CBU - Physics, Computer Science and Chemistry Student
