如果服务器的物理内存允许,可以通过修改 MySQL 的配置文件来增加缓冲池的大小。找到my.cnf或my.ini文件(根据操作系统的不同,文件名可能会有所不同),在其中添加或修改如下配置项: [mysqld] innodb_buffer_pool_size = 4G 1. 2. 将4G替换为你希望设置的缓冲池大小。 重新启动 MySQL 服务 在修改完配置文件后,...

In the below example screenshot captured from my local PMM GUI, you can see that the free pages inside the buffer pool are almost empty at different points in time which is one of the causes behind this situation as explained above. This data is available from the InnoDB Buffer Pool Pages...
如果在 Flags 中设置了标志DEBUG_SRCFILE_SYMBOL_TOKEN,Buffer 将接收与文件令牌 FileToken 关联的名为 File 的变量的值。 如果缓冲区NULL,则不会返回此信息。 [in] BufferSize 指定缓冲区 缓冲区的大小(以字符为单位)。 此大小包括“\0”终止字符的空间。 如果 Buffer 为NULL,则忽略此参数。 ...
比这更有效的一种方法是 myCollection.toArray(new Foo[myCollection.size()]),如果数组的长度足够大就可以直接把集合中的内容包装到数组中直接返回从而避免了第二次创建一个新的数组来存放集合中值。 15.SBSC: Method concatenates strings using + in a loop (SBSC_USE_STRINGBUFFER_CONCATENATION) 在循环中...
