Performance investigations: the problem, the diagnosis, the reported result, and what the evidence supports.
Performance and reliability
Reported worst-case latency: approximately 2 s → 0.2 s after a one-line fix. The async path blocked a thread pool outside the existing measurements; the retrospective keeps the original account’s measurement limits visible.
Reported certificate-validation latency: approximately 450 ms → 45 ms. Profiling exposed a caching gap in a desktop workflow. The full benchmark setup and correctness checks are not provided in the account.
Approximately 30,000 concurrent connections were established with low request frequency and reported memory pressure. This experiment explores connection limits; the count does not establish sustained useful-work capacity.
