Transparent Hugepages(THP)是Linux内核提供的一种内存管理机制,旨在通过自动创建、管理和使用大页(Hugepages)来提高内存分配效率和性能。与传统的Hugepages不同,THP不需要应用程序进行特殊配置或修改,它会自动为大内存分配请求提供大页支持,从而实现“透明”的大页管理。 2. 说明THP设置为"always"的含义 当THP设置为...

禁用hugepage: 自CentOS6版本开始引入了Transparent Huge Pages(THP),从CentOS7版本开始,该特性默认就会启用。尽管THP的本意是为提升内存的性能,不过某些数据库厂商还是建议直接关闭THP(比如说Oracle、MariaDB、MongoDB等),否则可能会导致性能出现下降。 临时关闭(重启服务生效): ...
Hi Sinisa, I've followedhttps://dev.mysql.com/doc/refman/8.0/en/large-page-support.html. Large pages support is working if innodb_buffer_pool_chunk_size is not producing shared memory segments large than 4GB. I'm also able to create shared memory segments on linux large than 4GB: // ...

it’s crucial that you add a rate limiter to your app. Not doing so could be detrimental, particularly if you’re using an API related to artificial intelligence features. For example, I recently worked on a side project that used an AI-related API. I received a huge amount of traffic ...
