Empirical measurements show that in large Smalltalk programs about 1/3 of all send sites in active methods remain unlinked, and of the remaining 2/3, 90% are monomorphic, 9% polymorphic and 1% (0.9%) are megamorphic.
根据测量显示，在大型Smalltalk程序中，所有活动方法的发送点有大约1/3维持未链接，其余2/3中，90%为单态（monomorphic），9%为多态（polymorphic），1%（准确来说0.9%）为复态（megamorphic）。
