Python的MySQL驅動pymysql與mysqlclient性能對比

Python版本3.6

測試語句：

select * from FOO;

 

mysql終端直接執行:

46410 rows in set (0.10 sec)

 

 

python程序需安裝profilehooks進行調用耗時分析

 

pymysql驅動測試程序：

# 安裝：pip install pymysql

from profilehooks import profile
import pymysql.cursors
import pymysql
connection = pymysql.connect(host='localhost', user='root', db='foo')
c = connection.cursor()

@profile(immediate=True)
def read_by_pymysql():
    c.execute("select * from FOO;")
    res = c.fetchall()



read_by_pymysql()

分析結果：耗時2.4s，與原始mysql讀取差一個數量級

 

 

mysqlclient驅動測試程序：

# 安裝：pip install mysqlclient 或 pip install git+https://github.com/PyMySQL/mysqlclient-python.git

from profilehooks import profile
import MySQLdb

connection = MySQLdb.connect(host='localhost', user='root', db='foo')
c = connection.cursor()

@profile(immediate=True)
def read_by_mysqlclient():
    c.execute("select * from FOO;")
    res = c.fetchall()



read_by_mysqlclient()

 

分析結果：耗時0.4s, 和mysql直接執行基本在同一量級

 

 

綜上，mysqlclient的性能要好於pymsql
