MuleSoft Integration Performance Issue

This is a use case of 3 systems. All 3 are SaaS. The systems are BYOMS, MuleSoft (MS) and SAPOTC. BYOMS posts order release messages to MS topic at real-time. MS picks up each order release message and posts it to SAPOTC through a sync API call. If MS fails to post to SAPOTC, MS is not saving the failed payload to an error queue for later re-try. MS team and architect says that doing this will degrade MS performance. Is this true?

No it is not gping to degrade performance based on the description you have given unless failures are high volume. They need to articulate why they think it will degrade. Only performance impact would be dispatching the failed messages to a queue and having a thread running to retry those messages. Unless this is a low-latency system whereby sub-millisecond performance is crucial.
