This is an attempt to implement this challenge in Swift. I took the original requirements & test data, and tried to make it run in reasonable time.
Right now it takes ~6.5s on MacBook Pro M1 to process the data:
hyperfine .build/release/1brc-swift ok 4s 16:50:04
Benchmark 1: .build/release/1brc-swift
Time (mean ± σ): 6.515 s ± 0.060 s [User: 52.862 s, System: 4.566 s]
Range (min … max): 6.460 s … 6.645 s 10 runsAnd ~8.8s on 10K version of the data:
hyperfine .build/release/1brc-swift ok 15:37:24
Benchmark 1: .build/release/1brc-swift
Time (mean ± σ): 8.786 s ± 0.097 s [User: 72.891 s, System: 5.290 s]
Range (min … max): 8.685 s … 9.037 s 10 runs- Generate measurements.txt (or measurements3.txt for 10k version) file using script from the original repo.
- Run the following command:
swift build -c release && time .build/release/1brc-swift /path/to/measurements.txt
