Expected behaviour

json rpc request method eth_getBlockByNumber Use methods to request data, return data in seconds, and support a considerable amount of concurrency

Actual behaviour

Tested on the same server, bor concurrency is 60k/reqs per second , but erigon is only 9k/reqs under this method, and the return time is very long bor: k6: 60k/reqs net upload speed: 20M/s erigon k6: 9s/reqs net upload speed: 900M/s

The network used here is very strange. According to the block data size and request rate, this large body will not be returned to the requester.

Steps to reproduce the behaviour

Use the k6 load tool to run the following script, you need to modify the IP and block height in the script

1. do you request historical blocks or recent blocks?
2. try reduce --db.read.concurrency to default value
3. try add --pprof flag to rpcdaemon, start load test, and show us result of go tool pprof -png http://127.0.0.1:6060/debug/pprof/profile\?seconds\=20 > cpu.png
4. "bor concurrency is 60k/reqs per second" - what is "bor concurrency"?
