    Every time I empty my trash using Secure Empty, my macbook slows down by a significant degree to a painfully slow pace. What is causing this?

    Secure Emptying the Trash overwrites the sectors previously populated by your data with gibberish. This takes processor power.

    Normal Empty Trash just marks the sectors to be overwritten as needed.

    Normal EMpty Trash doesn't actually delete them, just makes OS X to see them as free space. IMO normal is fine, unless you have some very secret files

    Empty Trash just tells the OS that these files can be written over at a later date. They aren't actually deleted (read overwritten) until the OS needs to put something there.

    Secure Empty Trash actually deletes the file right there by overwriting it with 0's, once, I believe. And in Disk Utility you can overwrite it 1, 7, or 35 times I believe for security purposes.
