Benchmarks vs other CL libraries

Speed and memory comparison of qbase64 with cl-base64 and s-base64.

System

• Processor: 2.3 GHz Intel Core i5
• Memory: 8 GB 2133 MHz LPDDR3
• OS: macOS 10.13.1
• SBCL: 1.4.1
• Library versions
  • qbase64: 0.1.1
  • cl-base64: 3.1
  • s-base64: 2

Running

In the benchmark/ directory, create a 100 MB binary file called test.bin and its base64 encoded version called test-base64.txt.

Run the following command:

sbcl --load benchmark.lisp --eval '(base64-benchmark::run! (list "encode" "decode") (list "qbase64" "cl-base64" "s-base64"))' --quit
