How to reduce lag in Network Transform Componented Player in UNET?

Its a UNET multi-player racing game,I’m using Network Transform Component to sync player position between server and clients.But the other player movement is very laggy and jittery to the local player.I have changed all values in the inspector but I cant make the desired effect.
Below is my settings of Network Transform Component .

Check the channel you are using to send this data and perhaps adjust it to be more reliable. Even try different channel types.

I see your Interpolate value on movements is quite low. Have you tried a larger value? Your send rate is probably quite high. Reduce this and let the Interpolation fill in the gaps.

Change your Send Rate to 10, that’s what Photon uses and it works pretty smooth, if that don’t work, gradually raise it higher. 30 is quite high.
