I have a git tree (https://github.com/sitsofe/fio/commits/proc_group ) that adds processor group support to fio CPU setting but to do so it introduces a flag to target the build to Windows 7 and sets it to be the default. If this change goes in it will mean if you would need to explicitly set a flag to have an fio that will work for WinXP/Vista/2003/2008 (before R2) etc. If you have time, any feedback would be useful. If I don't hear any complaints I'll send a pull request to Jens in a day or two. -- Sitsofe | http://sucs.org/~sits/ -- 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
