GitLab is a popular open-source software development platform that includes a CI/CD (continuous integration and continuous delivery) system. GitLab runners are a key component of this system, as they are responsible for executing CI/CD jobs.

However, if your GitLab runners are slow, it can have a negative impact on the performance of your CI/CD pipeline. This can lead to delays in deployments, which can in turn lead to lost productivity and revenue.

If you're struggling with slow GitLab runners, you're not alone. Many users face this issue due to various reasons, such as CPU limitations, low memory, or network pressure. This is why we created our own high performance cloud-based gitlab runners company.

To get a clearer understanding of why your runners might be slow, check out our article on the topic. We discuss typical causes and offer pointers for enhancing performance.

By following these tips, you can improve the performance of your GitLab runners and ensure that your CI/CD pipeline runs smoothly.

Understanding the Issue with Slow GitLab Runners

The key to your development process's effectiveness and efficiency lies in the speed of your Continuous Integration/Continuous Deployment (CI/CD) pipelines. However, if you're using self-hosted GitLab runners, you might find that their performance is slower than expected. The reasons for this could be numerous, ranging from hardware limitations to network bottlenecks and even poor configuration. Understanding these causes is the first step towards optimizing your GitLab runners and streamlining your CI/CD pipelines.

Solving Hardware Limitations

One of the most common reasons for slow GitLab runner performance is the inadequate hardware resources of the hosting machine. If your runners are running on underpowered machines, they will struggle to complete jobs quickly, particularly for CPU-intensive or memory-intensive jobs. To address this issue, it's essential to invest in high-performance hardware with ample CPU and memory resources. Upgrading your hosting machine to a more powerful configuration can significantly improve your GitLab runner's performance and decrease wait times.

Addressing Network Bottlenecks

Another crucial factor that can slow down GitLab runners is network congestion. If multiple runners are competing for the same network resources or if your network infrastructure is suboptimal, your runners' performance will inevitably suffer. To optimize your network, consider investing in high-speed internet connections and using load balancers to distribute network traffic across multiple runners. A well-optimized network can help improve the performance of your GitLab runners by reducing latency and ensuring faster data transfer speeds.

Eliminating Misconfigurations

Poorly configured GitLab runners can also lead to performance issues. Ensuring your runners are correctly configured is essential for optimal performance. It's crucial to review and update your runners' settings regularly, including optimizing the runner's concurrency level and fine-tuning cache settings. Making sure that your runners are correctly configured to match your project's needs can lead to significant improvements in your CI/CD pipeline performance.

Refactoring Inefficient Code

Inefficient code can be a significant bottleneck in the CI/CD pipeline. If your build scripts are not well-optimized, they can slow down your GitLab runners. Consider refactoring your code and optimizing your build scripts to improve performance. Simple actions like removing redundant code or optimizing database queries can have a significant impact on your runner's performance.

Unlocking the Power of Parallelization

One of the most effective ways to boost the performance of your GitLab runners is to leverage parallelization. By running multiple jobs simultaneously on different runners, you can dramatically reduce the overall execution time of your CI/CD pipeline. GitLab supports parallel job execution out of the box, so take advantage of this feature to optimize your pipeline and reduce wait times.

Cloud-Runner: Your Solution for High-Performance GitLab Runners

While optimizing your self-hosted GitLab runners can significantly improve performance, there's an even better solution - Cloud-Runner. Cloud-Runner offers high-performance managed GitLab runners optimized for CI/CD workloads. With dedicated resources, multithreading support, and high-speed network connections, Cloud-Runner can provide faster pipeline execution and shorter wait times.

Cloud-Runner also offers a unique feature for those with self-hosted GitLab instances - it can set up VPNs to private networks, allowing seamless communication between your self-hosted GitLab instance and the Cloud-Runner managed runners. This provides a hassle-free solution for faster pipeline execution without sacrificing the privacy and security of your self-hosted GitLab instance.


Improving the performance of your GitLab runners is crucial for efficient and effective CI/CD pipelines. By addressing hardware limitations, optimizing network infrastructure, correcting configurations, refactoring scripts, and leveraging parallelization, you can significantly boost your runner's performance. However, for a truly hassle-free and high-performance solution, consider Cloud-Runner's managed GitLab runners. With Cloud-Runner, you can enjoy faster, more reliable CI/CD pipelines without the need for constant optimization and maintenance.
