Well having it printed every second or so indicates you are pretty severely thrashing the cache, which can certainly impact performance. For example drawing your UI may not be fitting in the cache so each frame you draw requires re-rendering glyphs back in to the cache. If that is the case, look at doing things like reducing the number of distinct font sizes or families/styles you are using to have less impact on the cache.
