I am using a mid-2012 MBP 13in with no retina display, running OS X 10.8.3. Everything was fine until I was watching a video clip on Facebook. Everything just froze, except the mouse pointer can still move, but I can't do anything else. So I was forced to long press the power button to shut the machine down. After that, the whole system was ridiculously slow.
I can boot into my own account, but starting/running/closing any program takes ages. Also, when I tried to mount a
.dmg
. I was given a error message like 'No suitable file system.' I know I can just re-install the by booting into the recovery partition, but I'll take that as my last resort.

Aug 7, 2018 - Mac is Running Slow due to Lack of Hard Drive Space. Running out of space may not just ruin your system performance—it can also cause the applications you're working with to crash. That happens because macOS is constantly swapping memory to disk, especially for setups with low initial RAM.

It turns out to be a hardware problem. After getting frustrated with the extremely slow response, I reinstalled OS X via the recovery tool. But that doesn't last long - it starts to get slower (but not as slow as this case), and the Disk Utility complains that 'This drive has a hardware problem that can't be repaired.' So I send my MacBook back to Apple and they replace the hard-drive for me and it was covered by warranty.

Check Activity Monitor for what processes maybe slowing the system down. Be sure to switch from 'My Processes' to 'All Processes' at the top of the Activity Monitor window.
