3) Generate code for the relevant benchmark protocol buffer, e.g.
$ protoc --java_out=tmp google_size.proto google_speed.proto
$ protoc --java_out=tmp google_size.proto
4) Build the generated code, e.g.
$ cd tmp
$ javac -d . -cp ../protobuf.jar benchmarks/*.java
$ 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 .;../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
$ java -cp tmp:protobuf.jar com.google.protocolbuffers.ProtoBench \
'benchmarks.GoogleSize$SizeMessage1' google_message1.dat \
'benchmarks.GoogleSize$SizeMessage2' google_message2.dat
