[opus] PLC

We have implemented Opus Codec with a 48 ksps and 5 ms frame running on a C5535 for a radio link. The decode time takes about 2ms, which is fine. However if PLC enabled and there is a lost packet this increases to over 6 ms, which is a major problem for our radio link. Is there any options / optimisations that make the decode time more equal when a lost packet occurs with PLC?

Many thanks
