303-303: Verify the impact on resource utilization.
While reducing the polling interval will help detect idle states faster, polling too frequently might increase CPU usage. Consider adding resource utilization metrics to validate that 5 seconds is not too aggressive.
Consider these improvements:
- Add logging of detection timing for performance analysis
- Consider making the interval configurable through the config file
- Add resource utilization metrics during the idle detection phase
Example implementation:
def detect_idle_halted(idle_blocks: int, interval: int, chain_halt_interval=120):
"""
returns if the chain is empty for consecutive idle_blocks, or halted.
idle_blocks: the number of consecutive empty blocks to check
interval: poll interval in seconds (default: 5)
chain_halt_interval: the chain is considered halted if no new block for this time
"""
start_time = time.time()
last_time = start_time
prev_height = 0
poll_count = 0
while True:
poll_count += 1
latest = block_height()
if latest > prev_height:
prev_height = latest
last_time = time.time()
print(f"current block {latest} (polls: {poll_count}, " \
f"elapsed: {time.time() - start_time:.2f}s)")

303-303: Consider documenting the rationale for the polling interval change.
The reduction in polling interval from 20 to 5 seconds will help detect chain idle states more quickly, aligning with the PR's objective to reduce benchmark duration. However, it's worth documenting why 5 seconds was chosen as the optimal interval.
Let's verify the impact of this change on the chain's performance:
✅ Verification successful
The polling interval change is well-documented and appropriate
The function's documentation clearly explains the purpose of the interval parameter for polling. The change from 20 to 5 seconds is reasonable because:
- The function is used to detect chain idle state after sending transactions
- It's called in two contexts: after sending a batch of transactions and before process termination
- The shorter interval aligns with the PR's goal of reducing benchmark duration
- The function has built-in protection against chain halts with a separate
chain_halt_intervalparameter (120s)
