API Health
Tracks transient errors encountered during test execution. Tests retry on failures to ensure accurate results.
| Metric | Value |
|---|---|
| Health Score | 0/100 |
| Total Retries | 58 |
| Rate Limit (429) | 0 |
| Server Error (5xx) | 58 |
| Timeout | 0 |
| Connection | 0 |
| Tests Needing Retries | 78 |
Interpretation:
- Score 95-100: API is healthy, minimal transient errors
- Score 80-94: Some API instability, but tests recovered via retry
- Score < 80: Significant API issues affecting test reliability
Test Duration by Language
The primary performance metric - how long each language takes to run its full test suite (15 tests per language).
Key observations:
- GO and GROOVY are outliers at 90+ seconds
- Most languages cluster between 20-40 seconds
- Compiled languages (red) tend to be faster than interpreted (blue)
- FORTRAN is the fastest at 107 seconds
Compiled vs Interpreted
Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
Findings:
- 20 compiled languages vs 22 interpreted
- Compiled languages have lower median execution time
- Interpreted languages show more variance (wider spread)
- The white diamond marks the mean for each category
Duration Distribution
Histogram showing how test durations are distributed across all 43 languages.
Distribution analysis:
- Most languages complete in 20-35 seconds (the peak)
- Mean (green dashed) and median (blue dotted) are close together
- Long tail on the right from slow outliers (go, groovy)
Speed Leaders
Side-by-side comparison of the 10 slowest and 10 fastest languages.
Slowest (left): GO, GROOVY, AWK, JAVASCRIPT, ERLANG Fastest (right): FORTRAN, CSHARP, BASH, OCAML, PYTHON
Queue vs Execution Time
Scatter plot showing the relationship between CI queue wait time and actual test execution time.
Notes:
- Queue time is how long the job waited for a runner
- Most jobs had similar queue times (clustered vertically)
- Outliers labeled - go and groovy took longest to execute regardless of queue time
