尝试使用LOAD DATA INFILE将2Gb txt文件加载到MySQL中，并且它需要> 2天。你们中的任何一位专家都知道我需要做些什么来加快数据加载速度？是否有一些设置我可以更改以最大化CPU使用率？

2G文件无法加载需要数天。它应该只需要几分钟，最坏的情况。
您正在使用MySQL 5.6，但您仍在使用MySQL 5.5的默认设置。他们真的不够。
我建议至少为初学者更改这些设置：
你需要重新启动mysqld才能使这些生效。

你的延迟是因为对于每个插入，系统必须检查完整性，约束等。例如，每次插入发生时，索引都会重建......现在这只是一个例子。
如果您可以保证您的数据符合完整性限制，那么我就是这样做的。首先确保此时其他用户没有使用该数据库，这是您需要做的事情：
这可能非常棘手，因此使用脚本执行此操作应该是最佳选择。
