刚才Management Studio正好死掉了，出来下面这么个框：

---------------------------
SqlWb.exe - Common Language Runtime Debugging Services
---------------------------
Application has generated an exception that could not be handled.

Process ID=0xfa8 (4008), Thread ID=0x8c0 (2240).

Click OK to terminate the application.
Click CANCEL to debug the application.
---------------------------
OK   Cancel

果然是.net写的啊。
看来.net在大型应用方面，性能不容乐观。我机器是讯驰1.8，1g内存，都那么慢。
