# Protobuf Performance
The following benchmark test results were produced on a workstation utilizing an Intel® Xeon® Processor E5-2630 with 32GB of RAM.

This table contains the results of three separate languages:

* **C++** - For C++, there are three parsing methods:
	* **new** - This is for using a new operator for creating a message instance.
    * **new arena** - This is for using arena for creating a new message instance.
    * **reuse** - This is for reusing the same message instance for parsing.
* **Java** - For Java, there are three parsing/serialization methods:
	* **byte[]** - This is for parsing from a Byte Array.
    * **ByteString** - This is for parsing from a
    	com.google.protobuf.ByteString.
    * **InputStream** - This is for parsing from an InputStream.
* **Python** - For Python, there are three types of Python protobuf for testing:
	* **C++-generated-code** - This is for using C++ generated code of the
    	proto file as a dynamic linked library.
	* **C++-reflection** - This is for using C++ reflection, for which there's no
    	generated code, but still using C++ protobuf library as a dynamic linked
        library.
	* **pure-Python** - This is for the pure version of Python, which does not link with
    	any C++ protobuf library.

\* The cpp performance can be improved by using [tcmalloc](https://gperftools.github.io/gperftools/tcmalloc.html), please follow the (instruction)[https://github.com/protocolbuffers/protobuf/blob/master/benchmarks/README.md] to link with tcmalloc to get the faster result.
