c++ 2x faster than java on linux x64, with same machine/rate/config/images

X86-64 or ARM64? Both (Java and C++) are using parallel (or sequential) mode? Please share sample code you're using.

Please attach both logs (c++ and java)

c++.txt java.txt updated logs with same config

The only difference I see is the input: C++ uses RGB while Java uses BGR. In your Java code change ULTALPR_SDK_IMAGE_TYPE_BGRA32 to ULTALPR_SDK_IMAGE_TYPE_RGBA32 and ULTALPR_SDK_IMAGE_TYPE_BGR24 to ULTALPR_SDK_IMAGE_TYPE_RGB24 and share the Java logs again.

The change I'm asking to do isn't correct in production, so revert the change after collecting the logs.
