Remake: Unixbench

Preparando el servidor OpenVZ para la "I Noite Drupal & GNU/Linux" de Mugardos he encontrado una perla en Google Code: UnixBench. El objetivo de la aplicación es muy claro: ser un indicador de rendimiento para sistemas operativos basados en Unix partiendo de los resultados base de un SPARCstation 20-60(valor 10,0)Entre los múltiples tests realizados destacan:.- Dhrystone : Prueba de manejo de cadenas(sin coma flotante :P).- Whetstone: Mide la velocidad y efiencia de las operaciones con coma flotante..- Execl Throughput : mide la velocidad a la cual los datos pueden ser transferidos de un archivo a otro, con diferentes tamaños de búfer. Un consejo. No es un test rápido. En un AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ con frecuencia de 2,5ghz y 8GB de RAM el test necesitó más de 40 minutos para finalizar y mostrar resultados.Para curiosos, geek y demás fauna, ahí van los resultados: Version 5.1.3 Based on the Byte Magazine Unix Benchmark Multi-CPU version Version 5 revisions by Ian Smith, Sunnyvale, CA, USA January 13, 2011 johantheghost at yahoo period com1 x Dhrystone 2 using register variables 1 2 3 4 5 6 7 8 9 101 x Double-Precision Whetstone 1 2 3 4 5 6 7 8 9 101 x Execl Throughput 1 2 31 x File Copy 1024 bufsize 2000 maxblocks 1 2 31 x File Copy 256 bufsize 500 maxblocks 1 2 31 x File Copy 4096 bufsize 8000 maxblocks 1 2 31 x Pipe Throughput 1 2 3 4 5 6 7 8 9 101 x Pipe-based Context Switching 1 2 3 4 5 6 7 8 9 101 x Process Creation 1 2 31 x System Call Overhead 1 2 3 4 5 6 7 8 9 101 x Shell Scripts (1 concurrent) 1 2 31 x Shell Scripts (8 concurrent) 1 2 32 x Dhrystone 2 using register variables 1 2 3 4 5 6 7 8 9 102 x Double-Precision Whetstone 1 2 3 4 5 6 7 8 9 102 x Execl Throughput 1 2 32 x File Copy 1024 bufsize 2000 maxblocks 1 2 32 x File Copy 256 bufsize 500 maxblocks 1 2 32 x File Copy 4096 bufsize 8000 maxblocks 1 2 32 x Pipe Throughput 1 2 3 4 5 6 7 8 9 102 x Pipe-based Context Switching 1 2 3 4 5 6 7 8 9 102 x Process Creation 1 2 32 x System Call Overhead 1 2 3 4 5 6 7 8 9 102 x Shell Scripts (1 concurrent) 1 2 32 x Shell Scripts (8 concurrent) 1 2 3======================================================================== BYTE UNIX Benchmarks (Version 5.1.3) System: polinico: GNU/Linux OS: GNU/Linux -- 2.6.32-5-openvz-amd64 -- #1 SMP Mon Mar 7 22:25:57 UTC 2011 Machine: x86_64 (unknown) Language: en_US.utf8 (charmap="ANSI_X3.4-1968", collate="ANSI_X3.4-1968") CPU 0: AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ (2009.1 bogomips) Hyper-Threading, x86-64, MMX, AMD MMX, Physical Address Ext, SYSENTER/SYSEXIT, AMD virtualization, SYSCALL/SYSRET CPU 1: AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ (2009.1 bogomips) Hyper-Threading, x86-64, MMX, AMD MMX, Physical Address Ext, SYSENTER/SYSEXIT, AMD virtualization, SYSCALL/SYSRET 18:09:05 up 1:48, 3 users, load average: 0.25, 0.30, 0.23;
