Every rotating residential proxy plan provides you with a fixed number of ports. The Regular plan, for instance, includes 1000 ports which means that it allows you to run 1000 concurrent proxy connections.
You may need extra ports if your team has a larger number of users. In this case, every team member should be able to use their own ports. In the real world, every team member will need 2-3 ports at their disposal to do their job without any disruptions.
Another reason why you may need more than 1000 ports is if you want to collect a large volume of data within a short period of time. Let’s say you need to analyze the data from 1500 webpages. In this case, you will need 1500 ports to process and receive all the required data at the same time.
It’s important to remember that each port can handle no more than 30 requests per second. When ports are overloaded, any new requests will immediately be put on hold which can have a negative impact on the overall performance.
