Base64 Benchmark

This project measures the performance of various open source implementations.

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.
