Measuring Buffer 是一个用以缓冲各种数据的工具。主要特性有：
- direct support for TCP based network targets (IPv4 and IPv6)
- ability to send to multiple targets in parallel (distribution mode)
- support for multiple volumes
- I/O rate limitation
- high/low watermark based restart criteria
- configurable buffer size
- on the fly MD5 hash calculation
- highly efficient, multi-threaded implementation

一、缓冲池 15.5.1 Buffer Pool 缓冲池是主内存中的一个区域，InnoDB在访问表和索引数据时会在该区域进行缓存。缓冲池允许直接从内存访问频繁使用的数据，这加快了处理速度。在专用服务器上，通常会将高达80%的物理内存分配给缓冲池。 为了提高高容量读取操作的效率，缓冲池被划分为可能容纳多行的页面。为了提高缓存管理的效率，缓冲池被实现为页面的链接列表；很少使用的数据使用最近最少使用（

Choosing a good InnoDB log file size is key to InnoDB write performance. This can be done by measuring the amount of writes in the redo logs. You can find a detailed explanation in this post. To sum u
