The same two computers. 32 bit SSE2 rakesearch.exe real 6m15,250s user 0m0,000s sys 0m0,015s --------------------------- 64 bit SSE2 rakesearch.exe real 5m28,938s user 0m0,000s sys 0m0,015s

I tested this benchmark on two identical computers with Pentium Dual-Core CPU E5400 and 4 GB RAM. All settings of BIOS on both computers to do the same. CPU Thermal Trottling - Disabled Intel SpeedStep tech - Disabled On both computers for the period of the test BOINC and Antivirus was stopped. On first computer was installed 32 bit Windows 7 and 32 bit Cygwin Terminal. On second computer was installed 64 bit Windows 7 and 64 bit Cygwin64 Terminal. On 32 bit Windows was tested 32 bit rakesearch.exe from archive rakesearch_windows_32_ssse3_v11.zip On 64 bit Windows was tested 64 bit rakesearch.exe from archive rakesearch_windows_64_ssse3_v11.zip Results: --------------------------- 32 bit SSSE3 rakesearch.exe real 5m59,453s user 0m0,000s sys 0m0,015s --------------------------- 64 bit SSSE3 rakesearch.exe real 5m21,828s user 0m0,015s sys 0m0,000s

It can be run directly in Linux. On Windows you will need to install Cygwin. You can also try MinGW or MSYS, they also should work, but I did not try to use them - I prefer Cygwin. Thanks, Daniel. I will do tests in 2 - 3 weeks, when will the opportunity and time.

Планируется поставить Windows 7 на него. А какой лучше поставить? 32 или 64 разрядный? 32 или 64 разрядные оптимизированные под SSSE3 приложения RakeSearch будут считать быстрее? Проводились ли замеры скорости счёта на одном и том же компьютере но под 32 и под 64 разрядный Windows? I have a computer with 3 gigabytes of memory, Intel Pentium Dual Core E2220 processor and a new empty hard drive. I planned to install Windows 7 on this computer. What's version of Windows 7 is the best to install? 32 or 64 bit? 32 or 64 bit SSSE3-optimized RakeSearch applications will be count faster? Whether measurements were carried out of speed of crunching on the same computer but under 32 and under 64 bit Windows?
