Optimizing Proxies: Navigating Low and High Latency
The objective of a proxy is to provide privacy and protection for the user, but this does not have to come at the price of slow performance or inferior connectivity. Proxy server performance testing allows you to ensure that you are handling user requests effectively.

Understanding low and high latency in proxy services can help you determine where you stand. Latency is the rate at which data is transmitted between a user’s device and the destination server. Optimizing latency improves performance, but how do you do that? Let’s dive into what optimizing proxies for low latency means and what it could lead to for your project objectives.
What Is Latency?
Latency refers to the amount of time it takes data to move from one network to another network. It is measured between the user’s device and the data center. Latency is important for various applications, including for web pages and application function. It is also critical in proxy selection and use.
If a user is utilizing a proxy service, each of their requests will go through a third-party destination before making it to the target website. Proxy servers act as an intermediary between the user’s device and the destination website. That means it “could” take longer to capture information and process requests. However, by optimizing proxies, it is possible to minimize this to achieve low latency.
Low latency proxy services are able to move the request quickly, without limitation, and bring that data back to you with ease. A low latency network is one specifically designed to handle large amounts of data without delay, enabling ease of use in the most efficient manner possible.
Why Proxies Need to Be Low Latency
A proxy is a third-party intermediary in the process of transferring information from one device to the next. When you make a request with a proxy service in place, the request first goes to the proxy service before being routed to the target site. That small side-step enables you to hide your IP address. This makes it much harder for the target website to know who you are, where you are coming from, or what your intentions are.
Proxies can help with a wide range of tasks, such as reducing restrictions around your location or helping you to overcome blocked websites. They are also helpful in creating significant improvements to your security and privacy as you navigate the internet. The proxy service you select must be robust enough to keep up with your demands. One designed with low latency is able to handle more of the demand you will move through it (as well as others using the proxy server). As you are using a proxy, you do not want any delays in your experience, and latency is often a factor.
When we optimize latency, we ensure the entire process is smooth and straightforward. Latency is not about long lag times due to inefficiencies in site design. Rather, it’s measured in milliseconds. Specifically, we are looking at the time it takes for a request to be sent to the proxy server and then for the response to be received back from the target website’s destination server.
What Does Low Latency Mean to Your Proxy Use?
With low latency, you’re able to engage in activities in real-time without delays or slowdowns. That’s critical for some applications, such as real-world communication, online gaming, or live streaming of events. Low latency makes data-heavy tasks, such as web scraping, more efficient as well. With low latency, there’s no slowdown in this process.
What is good latency going to do for you?
- It allows for improved replay of videos or content.
- It allows you to interact in real-time without any difference in experience.
- It could allow you to capture real-time data, such as product inventory figures, in close-to-instant access.
- It may help you interact with customers in a more authentic manner without displaying your IP address.
- Low latency improves overall experience no matter what type of task you are engaging in.
What is good latency speed? When you start tracking and comparing options, you’ll see numerous figures displayed. Typically, good latency speed is 20 to 40 milliseconds (ms). The lower it is, the better it is. Great low latency happens with speeds of less than 20 ms. Anything between 40 and 100 ms is considered acceptable in other applications, though it can be limiting in proxy services. If you have a latency speed of over 100 ms, you have high latency, and that means experience is impacted.
Factors That Impact Latency with Proxies
A low latency proxy is the best choice for any type of use. Various factors impact the latency of a proxy service. Before you choose any service, consider the impact the following factors can have on your experience.
- Location: Low latency could be impacted by location. If the proxy server is further from the user, that could increase the amount of time it takes to transfer that request from one destination to the next. Simply, it has to go further, increasing time, just like distance on a roadway.
- Bandwidth considerations: Another roadway comparison applies here. If the proxy has low bandwidth capabilities, data transmits much slower. A slower speed limit or fewer lanes on a busy road can cause bandwidth options on highways. Limited bandwidth or resources on a proxy network will contribute to higher latency.
- Congestion on the network: Traffic is certainly going to slow down any commute. The same applies to proxies. If the network has a high level of users, that’s going to slow down the network. However, by increasing bandwidth to meet demand, it’s less likely that this will lead to limitations or higher latency.
- Proxy type: Also note that the type of proxy being used can play a role in the speed results. If you are using HTTP proxies, they are likely to have a lower level of latency than task-heavy tools like SOCKS proxies.
In these situations, it’s still critical to consider speed vs security. Some proxy services can move requests quickly. It may do that by stripping down security measures, making it easier for sensitive data exposure to occur. That may make these types of servers less beneficial in some situations.
Also, consider the types of applications you are using and how they can impact latency. Some tasks benefit from low latency more than others, such as:
- Any type of streaming application
- Real-time data management tasks
- Video-enabled applications
Considering all of these factors, it becomes necessary for users to understand a proxy service’s latency levels to be able to choose proper solutions for their applications and needs. Balancing security and privacy with speed and real-time interactions can be a tricky process.
How To Measure Latency
What is good latency speed? Lower is better, with our objective of being in the range of 20 to 40ms. You may be wondering how to find this speed. Several options exist for measuring latency with proxies, which ultimately allows you to choose the best solution for your needs. Some examples of the methods you can use to measure current proxy latency include:
- A simple ping test. Using a ping command, by opening the command prompt, you can input the proxy server’s IP address and then watch what happens. This will send packets to the server, and then the length of time it takes to get a response will be measured. You will see this labeled as the round-trip time, which is latency.
- Measuring tools. If you want more accuracy and details, consider choosing one of the various tools available to help you. GTmetrix is one of the most commonly recommended options. It takes virtually no time at all to test latency.
- Software. Some types of software can also help. These tools, like Apache JMeter, actually work through simulation. That means it can send multiple requests at one time, similar to what a true proxy service or website is likely to experience, and then can provide insight into speeds. You can use this to configure various conditions as well, such as project needs of different sizes.
How to Ensure You Have the Best Experience Possible
When choosing a proxy service, always seek out a solution that fits your needs, including the level of security and privacy that are right for your project as starting points. Then, weigh what’s most important to you. Typically, the best experience will focus on:
- Local servers close to you
- Higher bandwidth proxies that can handle more demand
- Proper selection of the type of proxy for your task and needs
