Description:
When creating a lot of tables in a single session performance gradually deteriorates when selecting a table.  Columns show immediately but can take up to 15 seconds for the definition to be free to use. App shows as not responding during this time and overloads a processor (on AMD Turion 64) 

How to repeat:
Create new model
Create 50+ tables in a single session
Select tables for edit at random

Suggested fix:
None

Thank you for the problem report. Please, send the results of Help > System Info.

MySQL Workbench SE for Windows version 5.1.9
Cairo Version: 1.5.12
Rendering Mode: GDI Rendering
OpenGL Driver Version: Not Detected
OS: Windows Vista/2008
CPU: 2x AMD Turion(tm) 64 X2 Mobile Technology TL-66, 3.3 GB RAM
Video adapter info:
Adapter type: ATI Radeon X1200 Series 
Chip Type: ATI Radeon X1200 Series (0x791F)
BIOS String: BK-ATI VER010.044.000.002.025007
Video Memory: 327680 KB

I can't repeat this with 64-bit XP having only 1G of RAM, 3GHz Xeon and much simpler Nvidia with 64M of video memory, even with 100+ tables... So, this is either Vista-related or ATI-related problem.
