Simulate Different Network Speed in Jmeter | 3G 4G 5G | Explained in Detail with Example | Perfology
How To stimulate different networks (2G, 3G ,4G, wifi , ethernet ) on Jmeter
#SimulateNetwork #Jmeter #Perfology
Jmeter gives you the option to stimulate different network speeds (2G, 3G ,4G ,wifi , Ethernet) based on your requirement .
1. Open bin folder of jmeter and search for user.properties file
2. Add the below code to your user.properties file
#Default
httpclient.socket.http.cps=0
httpclient.socket.https.cps=0
#2G network
httpclient.socket.http.cps=21888
httpclient.socket.https.cps=21888
#EDGE network
httpclient.socket.http.cps= 49152
httpclient.socket.https.cps= 49152
#3G network
httpclient.socket.http.cps= 256000
httpclient.socket.https.cps= 256000
#4G network
httpclient.socket.http.cps=21888
httpclient.socket.https.cps=21888
3. Restart jmeter
By default its value is set to zero which means it can allow maximum traffic and with no limitation.
Here’s the formula of calculating “cps”:
cps = (target bandwidth in kbps * 1024) / 8
For example: to emulate the GPRS cellular network speed (which is 171 Kbits/second downstream), the relevant CPS value would be: 21888 (171 * 1024/8)
To stimulate 2G network ,
Maximum network speed = 35 Kbits/sec downstream
the relevant CPS value would be: 4480 (35 * 1024/8)
minimum network speed = 171 Kbits/sec downstream
the relevant CPS value would be: 21888 (171 * 1024/8)
To stimulate EDGE network ,
Maximum network speed = 120 Kbits/sec downstream
the relevant CPS value would be: 15360 (120* 1024/8)
minimum network speed = 384 Kbits/sec downstream
the relevant CPS value would be: 49152 (384 * 1024/8)
To stimulate 3G network ,
Minimum network speed = 384 Kbits/sec downstream
the relevant CPS value would be: 49152 (384* 1024/8)
Maximum network speed = 2000 Kbits/sec downstream
the relevant CPS value would be: 256000 (2000 * 1024/8)
To stimulate 4G network ,
Minimum network speed = 3000 Kbits/sec downstream
the relevant CPS value would be: 384000 (3000* 1024/8)
Maximum network speed = 10000 Kbits/sec downstream
the relevant CPS value would be:1280000 (10000 * 1024/8)
To stimulate WIFI 802.11a/g ,
The relevant CPS value would be:1280000
To stimulate WIFI 802.11a/g ,
The relevant CPS value would be:6912000
To stimulate ADSL ,
The relevant CPS value would be:1024000
To stimulate 100MB Lan ,
The relevant CPS value would be:12800000
2. Alternatively, you can pass the properties’ values via the - J command line argument, like this:
jmeter -Jhttpclient.socket.http.cps=21888 -Jhttpclient.socket.https.cps=21888 -t /path/to/your/testplan.jmx
