Hello, Looking at fio for windows, we are pretty sure that the queue depth parameter is not working. We wanted to investigate this ourselves and prepare a fix, but the windows build is not working either. From a cygwin64 shell, make clean and make -j results in this: t/dedupe.c:13:23: fatal error: sys/ioctl.h: No such file or directory (although i see ioctl.h under cygwin64\usr\include\sys and under cygwin64\usr\i686-pc-cygwin\sys-root\usr\include\sys). Any idea why the build fails? -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
