How does SSLContext impact performance or memory usage?

SSLContext can significantly impact the performance and memory usage of applications that rely on secure connections (SSL/TLS). The way SSLContext is configured determines how efficiently the secure communication is handled, including aspects such as key management, cipher suite selection, and session handling.

For example, using more complex cipher suites may provide better security but can also increase the CPU usage, leading to potential performance bottlenecks. Additionally, if the SSLContext is not efficiently managed, such as not reusing sessions, it may also lead to increased memory usage due to the overhead of establishing new connections for every request.

To optimize performance, it is crucial to tune SSLContext settings, taking into account the specific use case and expected load. Effective SSL session management, selecting optimal cipher suites, and reusing SSLContext instances can mitigate performance issues.
