equipotential lines with implicit curves is very slow

Hi, I'm a physics teacher and I was attempting to create equipotential lines from electric field of two point charges and the solution I've found was to create the lines with implicit curves, with lists.

And I did it but the result was a heavy loaded page, very slow and freezing, so I've implemented it manually to see how it would behave:

Is it there a faster and lighter way to do it? I've search public materials and didn't found something similar. Perhaps it is necessary to optimize the code of implicit curves?
