set the innodb_buffer_pool to 3G - InnoDB will load as much data it can in the buffer pool.
将innodb_buffer_pool设置为3G - InnoDB将在缓冲池中加载尽可能多的数据。

Darhazer is right (I'd vote him up but don't have the rep points). It's generally recommended to set innodb_buffer_pool_size to 70-80% of memory although it's really more complicated than that since you need to account for how much RAM other parts of your system is actually using.
Darhazer是对的（我会投票给他，但没有重复点）。通常建议将innodb_buffer_pool_size设置为70-80％的内存，尽管它确实比这更复杂，因为您需要考虑系统其他部分实际使用的RAM量。
