Hi, I am trying to measure usb transfer throughput by timing file read operations from a usb flashdisk into main memory. The results seems to be imprecise and I suspect this is due to filesystem caching. How could I prohibit filesystem caching in the kernel? Do you know of any GPL'ed usb benchmarks? Maybe I should measure this in the kernel rather then application space? Thanks, Bahadir -- Kernelnewbies: Help each other learn about the Linux kernel.
