Look at Activity Monitor for apps / processes that are consuming large amounts of CPU or memory. Report back here if there are any you dont recognise or that shouldnt be using significant CPU but are.

As @satcomer said your main problem appears to be Google Chrome. Unfortunately not the best browser choice for Mac OS as its a known resource hog. Make sure you are using the latest version of Chrome if you need to use it.

You are running low on hard disk space, but 20GB free should be ok.

Runaway user process - A user process is using a large percentage of your CPU.

This may be Chrome causing this - However run Activity Monitor as suggested by @mick2 ( Use Spotlight to find and run) and click on the CPU tab. Click the %CPU column to sort the list to find the problem process.

As you said that it was ok a day ago a restart may resolve the problem.

I would also use Disk Utility to check the hard disk as you may have some issues that need to be fixed - A guide can be found here.

You're running several unnecessary pieces of software. All of these are obsolete, unsupported, or both. Uninstall them:

Another thing to think about: heat. One of my coworkers was complaining that builds were taking almost 2 hours instead of 20 minutes. The culprit was the heat wave that hit. No AC (not common here) meant his thin laptop just couldn’t stay cool enough to run fast.

If it is unusually hot where you are and you don’t have air conditioning, that could be at least part of your problem, and is definitely something that will vary day to day.
