refresh speed with large number of shape properties

[jimmyhopps]

Can someone help me understand the relationship between increased number of shape properties and refresh/drawing speed?  My org charts will have 200-5000 entities/shapes in them, and the use cases all entail toggling on/off and/or formatting shapes with various data attributes (e.g. fill color).  We are doing this in 2007 Standard (due to IT requirements) and can not use data linking.

a collegues tells me that if the number of properties we load into each shape starts going above about [5], the refresh time will be quite long.  However, I can imagine we would like to have 15 to 20 in total.  In our current code, a refresh on fill color takes about 30 seconds with 250 shapes. 

Any thoughts or reference material?

By shape properties do you mean Shape Data (aka Custom Properties)? These should make no (or very little) difference.
