Added comprehensive timeout handling to prevent hanging tests +3. Improved process cleanup with graceful termination, then kill if needed +4. Added better error handling in benchmark loops with specific exception types +5. Fixed response counting and metrics calculation to handle incomplete responses +6. Added timeout handling for individual test scenarios (60s each) +7. Enhanced process cleanup to avoid zombie processes +8. Added support for multiple serialization (None, pickle, json) and encoding (None, gzip) options +9.
