To avoid this situation, it is crucial that you run the migration smoothly, for example, by using bridging applications and by involving users right from the beginning.
为了避免这种情况，一定要平稳地迁移，例如使用桥接应用程序或让用户从一开始就参与迁移。
That is, SELECTs run with a 32-bit wrapper and the bridging code in a 64-bit environment were only 1% slower than the same queries run with a fenced 64-bit wrapper for the same source.
也就是说，在64位环境中，用32位包装器和桥接代码运行的SELECT比在相同数据源上用隔离的64位包装器运行的同样的查询仅慢1%。
