Very slow, use new version caffe2

[northeastsquare]

1. I clone new caffe2, compile a cpu version, and have: libCaffe2_CPU.a libCAFFE2_NNPACK.a libCAFFE2_PTHREADPOOL.a libcpufeatures.a
2. create script.ar: CREATE libcaffe2.a ADDLIB libCAFFE2_NNPACK.a ADDLIB libCAFFE2_PTHREADPOOL.a ADDLIB libcpufeatures.a ADDLIB libCaffe2_CPU.a SAVE END
3. ar -M < script.ar 4.replace AICamera libcaffe2.a with the generated libcaffe2.a 5.in AICamera2/app/src/main/cpp, make a soft link to the new caffe2 source code, copy some proto.pb.h files 7.run with android studio

the result, speed very slow， Can you give me help? Where am I wrong? @bwasti

By the way , recogition result not correct

[northeastsquare]

the size libcaffe2 which I use build_android.sh: 302257934 while you provide is : 31855028 nearly 10 times, why?

I got the same problem @northeastsquare

You're going to want to compile with -O3, let me add that to the CMakeLists in caffe2 :)

To do so yourself right now, edit this line to say

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -O3 -fPIC")

edit: waiting on tests to pass here https://github.com/caffe2/caffe2/pull/1000
