OK, redid my test.

This time put two images on a card, then executed the following script
several times:

*on* mouseUp

   *local* tstart

   *put* the milliseconds into tstart

   *repeat* 100000 times

      *get* the text of image id 1005

      *get* the text of image id 1006

   *end* *repeat*

   *answer* the milliseconds - tstart

*end* mouseUp


5.5.4: 96-99ms

6.0: 367-397ms

Even if this isn't testing the caching, something's up with 6.0
