## Overview
-The previous section on [diagnostic tools](diagnostic-tools.md) helped
business and operations personnel pinpoint specific slow SQL queries. This
section will introduce how to analyze the performance bottlenecks of slow SQL
to determine which part of the SQL execution process is causing the slowdown.
Powerful analysis tools are the foundation and guarantee for locating
performance issues.
+The previous section on [diagnostic tools](diagnostic-tools.md) helped
business and operations personnel pinpoint specific slow SQL queries. This
section will introduce how to analyze the performance bottlenecks of slow SQL
to determine which part of the SQL execution process is causing the slowdown.
The execution process of an SQL query can be roughly divided into two stages:
plan generation and plan execution. The former is responsible for generating
the execution plan, while the latter executes the specific plan. Issues in
either part can lead to performance bottlenecks. For example, if a poor plan is
generated, no matter how excellent the executor is, good performance cannot be
achieved. Similarly, even with a correct plan, inappropriate execution methods
can also lead to perform [...]

## 概述

的性能瓶颈进行分析，以确定具体慢在 SQL 执行的哪个环节。所以强大的分析工具是性能问题定位的基础和保障。

一条 SQL
的执行过程大致可以分为计划生成和计划执行两个阶段，前一部分负责生成执行计划，后一部分负责具体计划的执行。这两个部分出现问题都可能导致性能瓶颈的发生。比如生成了差计划，那么即使再优秀的执行器也不可能获得很好的性能。同样一个正确的计划，如果相应的执行手段不合适，也容易产生性能瓶颈。此外，执行器的性能和当前运行的硬件和系统架构有紧密的关系，一些基础设施的缺陷或者配置不正确也会导致性能问题。
