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:
- D and CPP are outliers at 90+ seconds
- Most languages cluster between 20-40 seconds
- Compiled languages (red) tend to be faster than interpreted (blue)
- COBOL is the fastest at 49 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 (d, cpp)
Speed Leaders
Side-by-side comparison of the 10 slowest and 10 fastest languages.
Slowest (left): D, CPP, RUBY, BASH, LUA Fastest (right): COBOL, CSHARP, OCAML, OBJC, KOTLIN
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 - d and cpp took longest to execute regardless of queue time
