very slow scrcpy. I connect via ip address.Adb latest version .

No source files, tests, or entry points are named. Start by reproducing scrcpy 2.0 over an IP connection with the reported XS97 Amlogic S905W2 on Android 11, then compare behavior with a local connection and gather enough performance details to identify the affected subsystem.
