Perhaps this has already been discussed, and I've just somehow overlooked the discussion about it in the past? If so, let me know and I'll lock this thread.
I was looking over the transaction volume at various fee levels at the following site:
https://jochen-hoenicke.de/queue/#2hI noticed a behavior for which I'm lacking a good explanation.
In the first 4 to 5 minutes after a block is solved, there is a sudden surge of transactions received at the 5 µBTC per byte to 7 µBTC per byte level (approximately 1200 transactions added during that 4 to 5 minute period). The rate of transactions at that fee level appears to be approximately 240 transactions to 300 transactions per minute.
Then until a block is solved, the number of transactions added at that fee level SUDDENLY drops to less than half that rate, about 100 transactions per minute. As soon as a block is solved, there is another burst of about 1200 or so transactions at the high 240 transactions to 300 transactions per minute for 4 or 5 minutes again.
I don't see this sudden post block burst at any other fee rate right now. The transaction count at all the rest of the fee levels seems to grow the same rate consistently.
It is difficult to see any detail on the charts that go back more than a day, so I'm not sure if the same behavior can be seen at different fee levels when the average fee level is higher or lower.
Does anyone have any good explanations of why there would be a temporary 4 to 5 minute burst of so many transactions at such a high fee level immediately after EVERY block, or why the rate of new transactions at that fee level would consistently and suddenly drop after 4 or 5 minutes?
You can see the effect in the chart below where the slope of the blue section suddenly changes:
