Is there a way to speed up Merge and Append Processes in Pro or ArcMap?

I am a heavy user of ArcMap and Pro. Using the Append or Merge tools have always seemed to be extremely slow. Merge/Append of spatial and non-spatial tables seems quite slow compared to much more complicated geo-processing the software is able to complete in a fraction of the time. As an example, today I was appending ~3k polygons to a base of ~450k polygons. Each data set has about 10 fields. The tables have exactly the same schema. The Append tool took 6.5 minutes to complete. An Append process of similar size in Microsoft Access would take about 10-seconds. Is there a simple way to improve the performance/speed of these tools?
