添加的代码会显着减慢处理时间

我将这些代码拼接在一起。它从工作簿中获取工作表,将它们作为单独的工作簿保存在新文件夹中,然后通过电子邮件将其发送给PM以进行操作。我盲目地写了它,不知道工作簿是如何构建的。然后我找到了工作簿(它是一个受限制的访问文件),有前4个工作表我需要忽略。我添加了另一个if循环来忽略包含字符串" IGNORE"的工作表。在单元格A2中。它在我添加这个if语句之前工作得如此之快,现在似乎需要更长的时间。我担心在我要实现它的工作簿上(20个工作表)会不合理地放慢速度。我想在调试模式下进行观察,我想,但任何帮助都将非常感激。这是代码:

Sub SplitWorkbook()
