I started simple by looking at open/close > performance, eg: I wonder what other good performance tests you can add to your test framework? creat/unlink is another easy one. And for each case, putting threads in their own cwd versus a common cwd are the variants. BTW. for these cases in your tests it will be nice if you can run on ramfs because that will isolate purely the vfs. Perhaps also include other filesystems as you get time, but I think ramfs is the most useful for us to start with. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
