Whats the difference between a high speed and normal crystal/ resonator??

I found no information in any of the pdf (sx spec sheet, sxkey manual, muratta, AN3) documents or forums searches regarding the differences and there is no information about the resonators/crystals being sold on the parallax web site. Although I did find out why Bean recomends OSCXT2 and these 2 threads were filled with good related info http://forums.parallax.com/showthread.php?p=537596· http://forums.parallax.com/showthread.php?p=536232
