UART IP make SOPC Builder starting slow?

I am trying to add the fifoed uart IP (cal uart) into my project, but i find the SOPC Builder started very slow. 21 uarts are used in my project and it needs more than 30 minites to start the SOPC Builder. it pauseed at "open system" window. Does anybody meet the problem, or anyone know how to resolve it. thanks very much.

    what version of Quartus II are you using? there was a bug in versions previous to 10.1 that caused slowness when using certain components such as the FIFOed UART. this is supposed to be fixed in 10.1, i haven't verified
