Cryptography Performance and Scalability Questions

Balancing cryptographic strength with system performance and scalability. Topics include algorithm and parameter choices for latency and throughput, session and key caching strategies, concurrency and parallelization approaches, use of hardware acceleration and cryptographic coprocessors, memory and resource constraints, benchmarking and profiling cryptographic operations, deployment trade offs such as synchronous versus asynchronous encryption, and monitoring of cryptographic performance in production. This also covers how optimizations interact with side channel risks and how to quantify and mitigate timing and other leakage introduced by performance work.
