please provide more info about your platform and model
be sure that the latest master code has been compiled in release mode and arm-neon enabled, targeted the right platform

[onexuan]

I use "sh build.sh" to compile after cd to the latest master folder.
arm-neon enabled
the targeted platform is right, I use armeabi-v7a in android
How to build it in release mode?

[onexuan]

I try build ncnn again use https://github.com/Tencent/ncnn/wiki/how-to-build
The same question, i build the latest release version and master version are show
Maybe the compilation environment is different

[onexuan]

Is it possible to build the latest master version for me? I can compare the tests.

[nihui]

so, what is your model network structure, mobilenet ? resnet ?

[nihui]

you can try running the ncnn benchmark and see how fast your platform is compared with others

[onexuan]

MTCNN mobilefacenet

I have test, this https://github.com/Tencent/ncnn/releases/tag/20180427 version is fastest that you built
I build some other versions by android-ndk-r17b, android-ndk-r16b, android-ndk-r15c, They are not performing well
I am waiting for your new release

[nihui]

new release package uploaded

[onexuan]

I have updated to the latest release version, It performs well
I think it may be that my build environment is different from yours. I am in mac.

[nihui]

please post your benchncnn result for each release version

[onexuan]

I have done a contrastive test, the release 20180704 is faster than 20180427, thread num is 2, improved about 60ms~90ms for me

You can try the latest ncnn code, with opt.use_packing_layout enabled, it should run faster
