Maximum number of inbound requests. default: 30
--max-tx-reqs <COUNT>
Max concurrent `GetPooledTransactions` requests.
[default: 130]
--max-tx-reqs-peer <COUNT>
Max concurrent `GetPooledTransactions` requests per peer.
[default: 1]

Default is 320 transaction hashes.
[default: 320]
--max-pending-imports <COUNT>
Max number of transactions to import concurrently.
[default: 4096]
--pooled-tx-response-soft-limit <BYTES>
Experimental, for usage in research. Sets the max accumulated byte size of transactions
to pack in one response.
Spec'd at 2MiB.
[default: 2097152]
--pooled-tx-pack-soft-limit <BYTES>
Experimental, for usage in research. Sets the max accumulated byte size of transactions to
request in one request.
Since `RLPx` protocol version 68, the byte size of a transaction is shared as metadata in a
transaction announcement (see `RLPx` specs). This allows a node to request a specific size
response.
By default, nodes request only 128 KiB worth of transactions, but should a peer request
more, up to 2 MiB, a node will answer with more than 128 KiB.
Default is 128 KiB.
