Jmeter模拟不同带宽

Jmeter自带模拟带宽设置，前提是当前的带宽>=要模拟的带宽，如：当前4m的宽带，只能模拟4m及以下的带宽；

设置方法：在user.properties文件，增加如下配置：

# Define characters per second > 0 to emulate slow connections
httpclient.socket.http.cps=49152
httpclient.socket.https.cps=49152

以上，是定义了一个Mobile data EDGE : 384 kbit/s的带宽；

计算cps公式

cps = (target bandwidth in kbps * 1024) / 8

 

Some examples:

Network bandwidth	cps value
Mobile data GPRS : 171 kbit/s	21888
Mobile data EDGE : 384 kbit/s	49152
Mobile data HSPA : 14,4 Mbp/s	1843200
Mobile data HSPA+ : 21 Mbp/s	2688000
Mobile data DC-HSPA+ : 42 Mbps	5376000
Mobile data LTE : 150 Mbp/s	19200000
WIFI 802.11a/g : 54 Mbit/s	6912000
WIFI 802.11n : 600 Mbit/s	76800000
Ethernet LAN ; 10 Mbit/s	1280000
Fast Ethernet : 100 Mbit/s	12800000
Gigabit Ethernet : 1 Gbit/s	128000000
10 Gigabit Ethernet : 10 Gbit/s	1280000000
100 Gigabit Ethernet : 100 Gbit/s	12800000000
WAN modems V.92 modems : 56 kbit/s	7168
ADSL : 8 Mbit/s	1024000
ADSL2 : 12 Mbit/s	1536000
ADSL2+ : 24 Mbit/s	3072000

 

Configuration summary:

1. 1. Ensure you use HttpClient 3.1 or HttpClient 4 implementations

   2. Configure bandwidth by defining the 2 properties above in <jmeter home>/bin/user.properties
