[🐛 Bug]: Running automation testing with Chrome and Selenium causing unusual increase in network traffic

[dhtt663]

What happened?

Steps to reproduce the problem

1. Set up the automation test project with the following:

• Selenium version 4.8.1

• Java version 17

• Chrome version 130.0.6723.116

• Run tests in parallel using 4 threads

• About 750 scenarios (around 30,000 steps)

2. Integrate the project with Jenkins using this setup:

• Jenkins version 2.462.3

3. After the tests finish running on Jenkins, check how much server bandwidth was used
   Problem Description
   We have Chrome (version 130.0.6723.116) and Jenkins (version 2.462.3) installed on our server running CloudLinux v8.10.0 STANDARD for running automation testing with Selenium. Daily network traffic is around 55GB to 70GB per day (we monitor using vnstat tool on Linux). But when we ran automation testing from Jenkins with Chrome it caused an increase in the total network traffic to over 150GB per day. More details from vnstat as below:

     day        rx      |     tx      |    total    |   avg. rate     
------------------------+-------------+-------------+---------------     
2024-12-01   122.80 GiB |    2.25 GiB |  125.06 GiB |   12.43 Mbit/s     
2024-12-02   148.36 GiB |    2.90 GiB |  151.25 GiB |   15.04 Mbit/s     
2024-12-03    80.06 GiB |    1.93 GiB |   81.99 GiB |    8.15 Mbit/s     
2024-12-04    79.93 GiB |    1.90 GiB |   81.83 GiB |    8.14 Mbit/s     
------------------------+-------------+-------------+---------------      
sum of 4    431.15 GiB  |    8.98 GiB |  440.13 GiB |

The first two lines are the network traffic we running automation testing and the last two are when not running.

However, the issue does not happen on the previous Chrome version. For example, Chrome version 130.0.6723.116
which we are using for current automation testing.
