macos macbook-pro ssd performance virtual-memory

                          I came across a thread about installing an SSD drive in MacBook Pro.  
Someone in the comments also recommended to disable the swap file but didn't say why:

    sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
    sudo rm /private/var/vm/swapfile*

I wonder why one would want to disable the swap file in Mac OS X.  
Does it increase performance? Stability?  
Any downsides?

Finally, does it make any sense to disable swap file when *not* using SSD?
