The garbage collector (GC) can greatly affect the performance of an application. Each memory allocation increases the GC load, therefore, it is needed to consider this during the development, please see recommendations from the Improve garbage collection performance page. The following options of the FIX Engine affect the GC load and can decrease the GC overhead:

• ReuseIncomingMessage (Please see the "Reusing FIX message instance for incoming messages" article of the Low Latency Best Practices page for details).
• UseMemoryPressure (Please see the "Do not use memory pressure" article of the Low Latency Best Practices page for details).
