Rails, when rendering partial, each output is rendered in a log. Is it a performance hit?

Question

For example, if the looping over @feed, which displays partial, you will see the following in the log:

Is it a performance hit? Is there a better way to handle this so that it doesn't output every time?

Yes, this is a performance hit. Highlighting a collection.
