Jobs performance

[luizcarlosfx]

Hello, in the Jobs.cs file there's an #if UNITY_JOBS which executes the jobs using the com.unity.jobs package, but it's disabled in my project. I wonder if it's good to enable it, in terms of performance.

Also, it seems like the unity jobs package is deprecated and I should use unity collections package now, but when I add the unity collections package to the project the #if UNITY_JOBS directive will not get enabled.

Can somebody enlighten me about this?
