However , code that is position independent may have poorer performance than code that is position dependent , if the image cannot be loaded at the preferred address
但是，如果映像无法在首选地址加载，则与位置无关的代码的性能比位置相关代码的性能差。
Code that is position independent can be loaded more quickly than code that is position dependent , if the image cannot be loaded at its preferred address , because relative addresses in position independent code are not patched if the image is loaded at an address other than its preferred address
如果映像无法在其首选地址加载，由于在首选地址之外的其他地址加载映像时，与位置无关的代码中的相对地址不需要进行修正，所以与位置无关的代码比位置相关代码加载得更快。
