mysql - Wamp 服务器 MySQL - 高性能 ~500mb

Question

我的 WampServer 2.5 有问题。 MySQL 5.6.16 消耗 500 MB RAM 内存。我没有数据库，全新安装。我在my.ini中设置了table_definition_cache = 400，但这并不能解决问题。这是我的.ini

看起来您可能已经看到建议进行此更改的答案并且更改是个好主意，但是:-

您是否安装了 64 位 WAMPServer？

如果您这样做了，那么在 64 位版本的 WAMPServer 上测试时会出现一个小错误。

在 64 位版本的 WAMPServer 中，MySQL 服务的名称更改为 wampmysqld64 但他们忘记相应地更改 my.ini 文件中的部分名称。

所以在 my.ini 中将部分名称更改为

# The MySQL server
[wampmysqld64]

MySQL 的工作方式是查看它自己的服务名称，然后在 my.ini 中查找与其服务名称匹配的部分标题下的配置设置。

这应该让 MySQL 注意到您的配置更改。
