This is a silly test IMNSHO, but if you really want to it you should also try compiling it on a UFS file system with softupdates. Additionaly, unless you are using native FreeBSD binaries instead of Linux binaries for the compiler, etc, the comparison isn't fair because there is some cost associated with making many syscalls, especialy open(2) which may result in extra reads. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
