Base64 Benchmark

This project measures the performance of various open source implementations.

It uses AndroidX Benchmark.

Currently tested implementations:

• Akka
• Aklomp Base64 (generic implementation). In C, wrapped in a custom made JNI library.
• AWS Java SDK
• BouncyCastle
• DatatypeConverterImpl from JAXB Reference Implementation
• IHarder
• MIDP (J2ME)
• OpenJDK Base64

Running

Open the project in Android Studio 3.4 or later, and run benchmarks as you usually would run tests: Ctrl-Shift-F10 (Mac: Ctrl-Shift-R)

Results

The following results were obtained by decoding 100 KiB (102,400 bytes) of random data.
