Does ProxyPass impact the size and performance of my Apache processes?
The ProxyPass client module is optimized in C for the best possible performance. It will nominally increase each individual Apache child’s memory footprint. Rigorous testing and real-world application has not shown any decrease in response speed. In fact, the opposite is true: precisely because the ProxyPass client module is so effective at detecting and denying brute-force password cracking attempts, the performance of your Apache server will increase dramatically.
