Our team uses Jenkins pipelines to build, scan, and deploy websites, serverless functions, microservices, and infrastructure to development or test environments. Depending on the project, the process takes roughly 20–40 minutes. We would like to improve overall feedback and deployment speed as development activity increases. Would switching tools—such as GitHub Actions—make a meaningful difference? We have concerns about workflow reliability, inputs, approval gates, and builds not triggering consistently. Our infrastructure is primarily on AWS, and moving to GitLab would be a major change, so we are mainly looking for practical ways to optimize the current setup or choose a faster alternative.

Jenkins is capable of being as fast as most other CI systems for many workloads. Before migrating, profile each stage and remove unnecessary work, duplicated setup, and avoidable environment provisioning. A different machine or platform will not automatically fix inefficient builds. The choice of tool is usually more about features, reliability, maintenance, and risk tolerance than raw execution speed.
Changing CI platforms probably won't make the pipeline faster by itself. Start by measuring where the time goes, then add dependency and artifact caching, build only the components affected by a change, and skip work for things like documentation-only updates. For larger projects, tools such as Bazel, Buck, or remote build caching can make a major difference. Also make sure the Jenkins agents have enough CPU, memory, and parallel capacity.
Parallelizing independent stages is often one of the easiest wins, especially for tests, scans, and deployments that do not depend on one another. It can also help to create a separate, tightly controlled emergency deployment path if the real concern is urgent fixes rather than normal development throughput. The best optimization depends on which kind of delay you are trying to solve.
If you still want to evaluate another platform, migrate one representative pipeline instead of moving everything at once. Most of the complexity will be around variables, secrets, environment approvals, and deployment rules rather than the basic build commands. It may also be worth refactoring reusable pipeline logic into portable scripts, such as Python or shell, so the build steps are less tied to Jenkins and easier to test or migrate later.
The goal is improving normal pipeline speed overall. Development teams are delivering more frequently, so we need the CI process to keep up.
