+# 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.
+
+The schema for the datasets is described in `benchmarks.proto`.
+
+Generate the data sets like so:
+
+```
+$ make
+$ ./generate-datasets
+Wrote dataset: dataset.google_message1_proto3.pb
+Wrote dataset: dataset.google_message1_proto2.pb
+Wrote dataset: dataset.google_message2.pb
+$
+```
+
+Each data set will be written to its own file.  Benchmarks will
+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
+   
+4) Build the generated code, e.g.
+   $ javac -d tmp -cp protobuf.jar tmp/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 tmp:protobuf.jar com.google.protocolbuffers.ProtoBench \
+       'benchmarks.GoogleSize$SizeMessage1' google_message1.dat \
+       'benchmarks.GoogleSize$SizeMessage2' google_message2.dat
+          
+6) Wait! Each test runs for around 30 seconds, and there are 8 tests
+   per class/data combination. The above command would therefore take
+   about 8 minutes to run.
+
+   
+Benchmarks available
+--------------------
+
+From Google:
+google_size.proto,
+messages google_message1.dat and google_message2.dat.
