WebAug 22, 2015 · By removing .As () and replacing with (T) (object), and replacing all the BitConverter work with bitwise work, we cut our work down to: 69% original time for byte. 73% original time for short. 80% original time for int. 90% original time for long. Also note that we returned the exact same values for all situations. WebBinaryReader always reads in little-endian, as you can see in the source code – it actually just calls BinaryPrimitives.ReadWhateverLittleEndian. Kind of wish they'd include big-endian versions by default… seems like it would be pretty easy. – Morgan Harris. May 11, 2024 at 0:30. 1.
