Re: [Gems-users] latency of L1_to_L2, L2_to_L1, L2_Replacement

["hongxia sun" <sunhx.seraph@xxxxxxxxx>]

It depends on the protocol you used. You can use "grep LATENCY" to find the latency parameters in your protocol.

Hi Hongxia,

The parameters you mentioned are for CMP protocols.
What about SMP protocols?

Thank you for your help!

Dave
