Many US airports planned before the 1970's had parallel runways built too close together for IFR in IMC operations. So SFO doesn't do parallel operations in foggy conditions, cutting the capacity in half. PHNL built 4R and 4L too close together. They used to hold small aircraft between the runways during parallel operations, but realized that a wingtip from a landing plane could hit the hold-short airplane. (Believe me, it was scary sitting out there between 2 737's landing in parallel at the same time - one in front and one behind you.) So now the hold-short blocks one runway, again cutting landing capacity.
