How unfortunate we missed your precious stance on that matter. Everybody knows that benchmarks are mostly useless /per se/, however it often occurs that comparative benchmarks may easily reveal some interesting differences. As for the interest of an experiment of pushing something to the limit for the sake of it, it may equally reveal interesting bugs. The fact that all filesystems in this tests didn't simply *fail* under the load is by itself revealing of the overall robustness and stability of these, the VFS and Linux kernel. = As a side note, were you using a slightly less harsh tone, you'd probably be help people being less reluctant to discuss those points more deeply. -- = ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
