# 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++-genereated-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.
