Html.Action() – Outputs string

Html.RenderAction() – Renders directly to response stream

If the action returns a large amount of HTML, then rendering directly to the response stream provides better performance than outputting a string.

So when would you use Html.Action if RenderAction gives better performance? – Oct 19 '10 at 21:50

@user76071 from [another question](http://stackoverflow.com/questions/5248183/html-partial-vs-html-renderpartial-html-action-vs-html-renderaction) with Action you can put the result in a variable or return it from a function. – David Kassa Mar 04 '13 at 15:25

Better performance? Barely. This is a bad case of premature optimization. Unless you are outputting a huge wiki article, the differences are negligible. Personally, I find Html.Action more readable and only use Html.RenderAction if I am in a code block. – Jordan Jul 08 '16 at 12:52
Below article In answer below, states RenderAction is better when rendering a lot of HTML, (like a partial View.) That's why I like it better. – user1161391 Nov 30 '18 at 21:53

The difference between the two is that Html.RenderAction will render the result directly to the Response (which is more efficient if the action returns a large amount of HTML) whereas Html.Action returns a string with the result.
