+# Protocol Buffers Benchmarks
+
+This directory contains benchmarking schemas and data sets that you
+can use to test a variety of performance scenarios against your
+protobuf language runtime. If you are looking for performance 
+numbers of officially support languages, see [here](
+https://github.com/google/protobuf/blob/master/docs/Performance.md)
+
+## Prerequisite
+
+First, you need to follow the instruction in the root directory's README to
+build your language's protobuf, then:
+
+### CPP
+You need to install [cmake](https://cmake.org/) before building the benchmark.
+
+We are using [google/benchmark](https://github.com/google/benchmark) as the
+benchmark tool for testing cpp. This will be automaticly made during build the
+cpp benchmark.
+
+The cpp protobuf performance can be improved by linking with [tcmalloc library](
+https://gperftools.github.io/gperftools/tcmalloc.html). For using tcmalloc, you
+need to build [gpertools](https://github.com/gperftools/gperftools) to generate
+libtcmallc.so library.
+
+### Java
+We're using maven to build the java benchmarks, which is the same as to build
+the Java protobuf. There're no other tools need to install. We're using
+[google/caliper](https://github.com/google/caliper) as benchmark tool, which
+can be automaticly included by maven.
+
+### Python
+We're using python C++ API for testing the generated
+CPP proto version of python protobuf, which is also a prerequisite for Python
+protobuf cpp implementation. You need to install the correct version of Python
+C++ extension package before run generated CPP proto version of Python
+protobuf's benchmark. e.g. under Ubuntu, you need to
+
+```
+$ sudo apt-get install python-dev
+$ sudo apt-get install python3-dev
+```
+And you also need to make sure `pkg-config` is installed.
+
+### Go
+Go protobufs are maintained at [github.com/golang/protobuf](
+http://github.com/golang/protobuf). If not done already, you need to install the 
+toolchain and the Go protoc-gen-go plugin for protoc. 
+
+To install protoc-gen-go, run:
+
+```
+$ go get -u github.com/golang/protobuf/protoc-gen-go
+$ export PATH=$PATH:$(go env GOPATH)/bin
+```
+
+The first command installs `protoc-gen-go` into the `bin` directory in your local `GOPATH`.
+The second command adds the `bin` directory to your `PATH` so that `protoc` can locate the plugin later.
+
+### Big data
+
+There's some optional big testing data which is not included in the directory
+initially, you need to run the following command to download the testing data:
+
+```
+$ ./download_data.sh
+```
+
+After doing this the big data file will automaticly generated in the
+benchmark directory.
+
+## Run instructions
+
+To run all the benchmark dataset:
+
+### Java:
+
+```
+$ make java
+```
+
+### CPP:
+
+```
+$ make cpp
+```
+
+For linking with tcmalloc:
+
+```
+$ env LD_PRELOAD={directory to libtcmalloc.so} make cpp
+```
+
+### Python:
+
+We have three versions of python protobuf implementation: pure python, cpp
+reflection and cpp generated code. To run these version benchmark, you need to:
+
+#### Pure Python:
+
+```
+$ make python-pure-python
+```
+
+#### CPP reflection:
+
+```
+$ make python-cpp-reflection
+```
+
+#### CPP generated code:
+
+```
+$ make python-cpp-generated-code
+```
+
+### Go
+```
+$ make go
+```
+
+To run a specific dataset or run with specific options:
+
+### Java:
+
+```
+$ make java-benchmark
+$ ./java-benchmark $(specific generated dataset file name) [$(caliper options)]
+```
+
+### CPP:
+
+```
+$ make cpp-benchmark
+$ ./cpp-benchmark $(specific generated dataset file name) [$(benchmark options)]
+```
+
+### Python:
+
+For Python benchmark we have `--json` for outputing the json result
+
+#### Pure Python:
+
+```
+$ make python-pure-python-benchmark
+$ ./python-pure-python-benchmark [--json] $(specific generated dataset file name)
+```
+
+#### CPP reflection:
+
+```
+$ make python-cpp-reflection-benchmark
+$ ./python-cpp-reflection-benchmark [--json] $(specific generated dataset file name)
+```
+
+#### CPP generated code:
+
+```
+$ make python-cpp-generated-code-benchmark
+$ ./python-cpp-generated-code-benchmark [--json] $(specific generated dataset file name)
+```
+
+### Go:
+```
+$ make go-benchmark
+$ ./go-benchmark $(specific generated dataset file name) [go testing options]
+```
+
+
+## Benchmark datasets
+
+Each data set is in the format of benchmarks.proto:
+
+1. name is the benchmark dataset's name.
+2. message_name is the benchmark's message type full name (including package and message name)
+3. payload is the list of raw data.
+
+The schema for the datasets is described in `benchmarks.proto`.
+
+Benchmark likely want to run several benchmarks against each data set (parse,
+serialize, possibly JSON, possibly using different APIs, etc).
+
+We would like to add more data sets.  In general we will favor data sets
+that make the overall suite diverse without being too large or having
+too many similar tests.  Ideally everyone can run through the entire
+suite without the test run getting too long.

-Contents
---------
-
-This folder contains three kinds of file:
-
-- Code, such as ProtoBench.java, to build the benchmarking framework.
-- Protocol buffer definitions (.proto files)
-- Sample data files
-
-If we end up with a lot of different benchmarks it may be worth
-separating these out info different directories, but while there are
-so few they might as well all be together.
-
-Running a benchmark (Java)
---------------------------
-
-1) Build protoc and the Java protocol buffer library. The examples
-   below assume a jar file (protobuf.jar) has been built and copied
-   into this directory.
-
-2) Build ProtoBench:
-   $ javac -d tmp -cp protobuf.jar ProtoBench.java
-   
-3) Generate code for the relevant benchmark protocol buffer, e.g.
-   $ protoc --java_out=tmp google_size.proto google_speed.proto
-   
-4) Build the generated code, e.g.
-   $ cd tmp
-   $ javac -d . -cp ../protobuf.jar benchmarks/*.java
-           
-5) Run the test. Arguments are given in pairs - the first argument
-   is the descriptor type; the second is the filename. For example:
-   $ java -cp .;../protobuf.jar com.google.protocolbuffers.ProtoBench
-          benchmarks.GoogleSize$SizeMessage1 ../google_message1.dat
-          benchmarks.GoogleSpeed$SpeedMessage1 ../google_message1.dat
-          benchmarks.GoogleSize$SizeMessage2 ../google_message2.dat
-          benchmarks.GoogleSpeed$SpeedMessage2 ../google_message2.dat
-          
-6) Wait! Each test runs for around 30 seconds, and there are 6 tests
-   per class/data combination. The above command would therefore take
-   about 12 minutes to run.
-
-   
-Benchmarks available
---------------------
-
-From Google:
-google_size.proto and google_speed.proto, messages
-google_message1.dat and google_message2.dat. The proto files are
-equivalent, but optimized differently.
