tiobench - I/O benchmark program

[TeLegrapH]

Estaba aburrido y como llevaba ya tiempo queriendo ver el rendimiento de mis tarjetas SD, he compilado el tiobench para la negrita (lo uso de vez en cuando en el curro para hacer benchmarking de discos SCSI y mola bastante ya que permite múltiples threads).

URL de la utilidad: http://sourceforge.net/projects/tiobench/

Compilado para la GP2X: http://www.2squid.com/gp2x/tiotest-0.3.3-gp2x.tar.gz

Para los que no tengan el kernel con soporte de red y por tanto no vayan a entrar por telnet, he añadido un script donde podéis modificar las opciones con las que queréis lanzar el programa. Dejará los resultados (después de esperar un poco :D hay que tener paciencia) en el fichero results.txt

Y como curiosidad adjunto los resultados, lanzando un solo thread escribiendo y leyendo un archivo de 1 Mbyte.

¿es posible poder indicar el valor en Mo/s y en Mb/s?

These are most likely because the data was read from the cache, and not the SD card, so will not give accurate results. The cache should be cleared between the write and read results to get the accurate figures. (looking at the source code for the SD driver, 41MB/s is impossible).

Si, ya me di cuenta ayer después de postear los resultados que no tenia mucho sentido.

No habia caido en el cacheo al usar ficheros tan pequeños y puse 1Mb por thread en el script de ejemplo simplemente para probar que la utilidad funcionaba bien.

Para evitar el cacheo y obtener resultados reales, hay que incrementar el tamaño del fichero a algo superior al tamaño de la memoria de la gp2x.

Edita el script de lanzado, y modifica la opción -f a 64 Mb o más.

Eso si, tardará bastante más en completarse el test.
