The numeric suffix on each label indicates the vCPU count (e.g. -8 = 8 vCPU). The label without a suffix is the 4 vCPU default and replaces ubuntu-latest and ubuntu-24.04.
All sizes run Ubuntu 24.04 on 5th Gen AMD EPYC.
Performance Characteristics
StarSling runners deliver excellent performance for most CI workloads:
- Web Applications (React, Next.js, Vue): Fast installs and builds
- Backend Services (Go, Rust, Java): Efficient parallel compilation
- Test Suites: Parallel test execution
Larger sizes (8 vCPU and above) are well-suited for monorepo builds, large test matrices, and compilation-heavy workloads.
Example Usage
runs-on: starsling-ubuntu-24.04For a larger size:
runs-on: starsling-ubuntu-24.04-8Optimization Tips
- Cache dependencies: Use
actions/cacheto avoid repeated downloads - Use matrix builds: Split tests across multiple runners for parallelism
- Right-size your runner: Larger isn't always better — measure before scaling up
