We are using RFA C++ 8.2.4.E1. To increase the throughput of our application we are looking for ways to improve its performance.

Can RFA be configured to send updates only when the underlying value has changed.
Hi Team, Our clients use ODC Real SDK(8.2.4.E1 & 8.2.1.L1), which receives market updates via the RFA libraries. Recently, the volume of updates we receive has grown drastically (likely due to increased market volatility). This high message rate is filling our event queue and causing memory pressure on client machines.…
