Description

This project benchmarks common data serialization formats using JMH.

The sample data is taken from here.

Formats

• Cap’n Proto
• EXI
• Fast Infoset
• Json (using Jackson)
• MessagePack
• Protostuff
• Protocol Buffers
• Apache Thrift
• XML (using JAXB, JAXB with Aalto, Jackson)
• Java Object serialization (functions as control group)

Thrift preparation

Thrift is a special case, because its code generator maven plugin expects the path of an installed Thrift library. Make sure it is installed.

Test cases

• Byte array (in memory) to Java Object
• Byte array (in memory, compressed with gzip) to Java Object
• Java Object to Byte array (in memory)
• Java Object to Byte array (in memory, compressed with gzip)

System Requirements

• JDK 11
• Maven

How to use?

1. Build the project (a self-contained executable JAR, which holds the benchmarks):

   # mvn package
   

2. Run all benchmarks:

   # java -jar target/serialization-format-benchmarks.jar
   

   Usage with options (java -jar target/serialization-format-benchmarks.jar info prints the following):

   Usage: serialization-format-benchmarks [options]
     Options:
       -c, --comp
         Benchmark with no compression (without), compression (with) or both
         (both)
         Default: both
         Possible Values: [without, with, both]
       -e, --exclude
         Comma separated regex list to exclude benchmarks from the run.
         Default: []
       -i, --include
         Comma separated regex list to include benchmark in the run. Default
         value runs all benchmarks
         Default: [Benchmarks]
