Shadow Speed Problem?

I am having an odd speed problem with Shadows, but can't quite figure out why. If anyone can explain or has ideas that would be appreciated.
Here is what happens.
When I add 1 Roman style Column (15.24 meters high) on a new mission terrain, it takes about 15-17 seconds to do a one time render of the shadow onto the terrain. When I add 6 more Columns the total render time is only about 30 seconds. I can deal with that since it is only once.
Now starting over with no Columns, I add a single large platform as its own object instance 50x50x10 meters which uses the default gray castle wall texture. Adding 1 Column on it, the render time of the shadow onto the platform is also about 15-17 seconds, but when I add the other 6 Columns on top of the platform, it takes over 5 minutes to render the shadows on the platform.
When all the renders are done the shadows look very nice, but I can't afford 5 minutes for 6 Columns when my completed area would have about 400+ Columns on the platform. I have to find another way.
If I can't figure it out, I am thinking of turning off Shadows while I am working and then let them render over night.
Anyone have an idea of why this happens what I could do? Thanks.

It was not clear when I started this thread, but thanks for the clarification. That is what I am finding also with all my tests. I have a better understanding of the system now and have concluded it is time to upgrade my system.
Thanks everyone!

Let us know if new hardware helps things perform better. :)

Can you post some screenshots of your problems?
Do you have the latest drivers?
Things will go more slowly on an oldish system like that!
