Ninja Subnet Addresses Duel Delays and Evaluation Speed Issues

The ninja subnet team implemented technical changes introducing per-round I/O overhead and adjusted rate-limiting parameters, while actively resolving duel evaluation speed regressions. Miners reported prolonged queues and evaluation times, prompting concurrency optimizations that reduced duel durations to 10-15 minutes. A new challenger's syntax errors caused solver failures, and discussions highlighted miner strategies contributing to queue congestion.

• •Increased diff-judge timeout to 300s and reduced task-generation throughput to 1/3rd capacity
• •Concurrency improvements cut evaluation speed to 10-15 minutes per duel
• •Read-token pool modifications risk faster rate-limit exhaustion for deployments relying on merge tokens
• •Miners flagged syntax errors in new challenger causing solver failures
• •Queue congestion attributed to multiple agent submissions by some miners
