Implement tx selection time of High scored txs

Implement a transaction selection time of high scored transactions

Current behaviour

Produced #23,192,821 / 300 tx / 0 om / 29,481,838 (1.5%) gas / (0xb9dbf8b76bec7e7f780559df0abe419df36f4726a50f61a4970745f1af466834) in 1.569s / Timing(started at 2025-09-
11T09:58:35.158638058Z, protocolWait=0ms, duplicateWorldState=31ms, preTxsSelection=3ms, txsSelection=1373ms, 
blockAssembled=31ms, importingBlock=129ms, notifyListeners=0ms, log=0ms)

Expected behaviour

Produced #23,192,821 / 300 tx / 0 om / 29,481,838 (1.5%) gas / 
(0xb9dbf8b76bec7e7f780559df0abe419df36f4726a50f61a4970745f1af466834) in 1.569s / Timing(started at

11T09:58:35.158638058Z, protocolWait=0ms, duplicateWorldState=31ms, preTxsSelection=3ms, 
txsSelection=1373ms, txsSelectionHighScore=950ms, 
blockAssembled=31ms, importingBlock=129ms, notifyListeners=0ms, log=0ms)

This helps to investigate the transaction selection time one there is a timeout to understand what time the transactions that were included in the block took in terms of selection time, example :

Produced #23,354,394 / 70 tx / 0 om / 2,785,671 (0.1%) gas / 
(0x051f72e4bff0c012e2c03fc9fcf4d476a3775689ce1329647439e26ec17280d6) in 2.014s / Timing(started at 
2025-09-15T09:13:46.954264875Z, protocolWait=46ms, duplicateWorldState=0ms, preTxsSelection=2ms, 
txsSelection=1923ms, blockAssembled=15ms, importingBlock=26ms, notifyListeners=0ms, log=0ms) 

I this case, there was a timeout but we don't know the real time it tool to select the 70 transactions

Transaction ... is processing for 1704ms, giving it 316ms grace time

Hi @macfarla , I want to work on this issue. Could you assign it to me?

Hi, @Shivang14d04 are you still working on these?

[Shivang14d04]

Hi, @AliZDev-v0, I wasn't able to work on it due to my exams. My current understanding of this issue is :

• I have to measure the time spent selecting high-scored transactions from the transaction pool.
• Store this measured duration in TransactionSelectionResults.
• Then I have to log this value alongside the existing block creation timings.

I will implement it and raise a pr as soon as possible.
