open documents is so slow

Hi,

I use InDesign CS6 on Mac OS 10.8.1. The app is installed on SSD. The start-up is very fast, but when I want open a document... I see the beachball for 2 seconds before the document (134 kb) was loaded. The document is located on a seperate HD, bu even when I place the document on the SSD... it's the same slow speed during the opening.

Help please... thanks.
