+# Performance
+This library is written in C++/CLI (aka. C++ Interop), which has better performance according to [Microsoft](https://learn.microsoft.com/en-us/cpp/dotnet/performance-considerations-for-interop-cpp). All the marshaling details are manually controlled for optimized performance and latency. The callback exposed the native pointer directly, which eliminate all of the unnecessary copies. It should has lower latency compared to other camera library using explicit P/Invoke.
