    Since this is just a test of unpacking and deleting lots of files... couldn't one do this test in Windows/Mac OSX to see how their file systems match up.

    Does anyone have any benchmarks comparing them?

    Imagine how quickly you can rm -rf / now...

    I honestly want to know if it is a huge increase, or a small increase.

    As in all things benchmarking related, the answer is: It depends. This will be significant for certain uses of your system, but unimportant for others. If you've got a very busy file server, a news server, or a build machine where you do alot of compilation, this will be very significant. For other tasks you might not even notice.

    This is a kernel change, so there won't be any ISOs. Why not just try it now?
