afaics rpc traffic is not limited

that's why I had to turn off public rpc on my linode, was eating all my bandwidth quota

RPC traffic has been really high on my nodes lately, luckily Hetzner has 20TB / month bandwidth

i think an rpc limit would be appreciated :)

I'll help 10 individuals on how to earn $25,000 in just 72 hours from the crypto/forex market. But you will pay me 10% commission when you receive your profit. if interested send me a direct message via Whatsapp by asking me HOW for more details on how to get started.. +1 (570) 801-0862

Not sure if this means anything, but I'm just so super happy about this latest fork. The devs did a fantastic job in all respects

Congratulations, and thank you

Hello !

<gingeropolous> "i think an rpc limit would be..." <- What does an rpc limit imply? Is it about limiting incoming transactions to our node?

Limit connection speed

Hello! I want to deploy my own node for a stratum servers.

1) What are the system requirements for the server?

2) What monerod parameters do I need to pay attention to in order to use all the server resources and get maximum performance?

Thank you.

For performance, --db-sync-mode (or similar name). It is somewhat conservative by default IIRC. Maybe not the best.

1) Fast SSD + a lot of RAM

2) p2pool recommends --disable-dns-checkpoints --enable-dns-blocklist

Is 32GB of RAM enough?

Yes.

This node is for personal use?

stratum server = I assume for pool mining

The node is for my own pool implementation. About 10 servers will pull for a block template each 0.01 sec.

it's better to use ZMQ instead of polling 100 times/second

Does the roc of node somehow cache the response to receiving a new template block?

For example, if the blocktemplate has not changed, then it returns the cached version.

Because of this pooling (100 times/second), can there be a heavy load on the node?

ZMQ block notification is sent immediately when a new block is received

getblocktemplate does use internal caching

IIRC it caches the result for 1 second, but the cache is cleared when a new block is received

Can you tell me exactly the caching time? Or suggest a place in the source code where I can look myself.

I want to try to pick up the pooling time in my current implementation.

And ofc I will try to see ZMQ.

ZMQ is much better than any polling

it'll get you a new block template faster than even 0.001 sec polling

what do you mean by "my own pool implementation"? New software, or just your private pool?

I will do research in my university. The topic is my own implementation of monero mining pool)

Want to get best performance in all aspects)

then check p2pool for how to work with ZMQ

moneromooo: The default value of "db-sync-mode" is `fast:async:250000000bytes`.

Should I use "fastes:async:<RAM size>"?

BTW should I use `--prune-blockchain` or it is not suitable for a node of mining pool?

mining pool can work with pruned blockchain

sech1: yeap. Thank you, bro!

db-sync-mode doesn't matter much once you're synced and mining

Good connectivity to the rest of the network is much more important for mining pool

First of all, connectivity to other major pools' nodes

How to choose "nbytes_per_sync" parameter?

And having own nodes in different regions (US east, west, Europe, Asia are bare minimum for a pool)

> Good connectivity to the rest of the network is much more important for mining pool

Yes, I know it. But I do not know how to connect to the nodes of other pools, I did not find information about this on the Internet.

Usually these are private nodes, as I understand it.

pools hide their nodes to avoid DDoS

but usually you can narrow it down to a single datacenter in each region

yep, it's logical)

and just run a node in the same datacenter and connect to everything that's listening on port 18080 there :)

But how can I get a good connectivity in terms of monerod parameters? For example, try to increase node peers counts and etc?

--add-priority-node IP:port

--add-priority-node=IP:port

After restarting a node, does it lose all the peers to which it has a connection?

I thought if I want to add some parameters (like `add-priority-node`), I will need to restart the node....

I don't know how to choose the --db-sync-node size. RAM size is ill advised though.

Hello, what to do is, I sent monero to my GUI wallet, but nothing comes, there is a hash of the transaction

Update your wallet

(Ensure gui version is v0.18.0.0 or higher)

All sockets/connections are interruptde on process end.

I have a patch somewhere which allows you to connect/disconnect a node at runtime. Not sure how current though.

Will monerod restore it after starting or not?

After restart, monreod will connect again, but not necessarily to the smae ones you had.

it will connect to known peers, but not necessarily the smae

lol, same typo :D

Must improve opsec...

IIRC there's a "whitelist" and a "greylist" of peers

whitelist is 1000 peers, it can try to connect to any of them

re: rpc traffic - I seem to be a broken record, said almost verbatim a year ago monero-project/monero #7388#issuecomment-922392476

selsta: started the review yesterday, will complete today

vtnerd: which patch?

the multisig "force" patch you pointed at yesterday

I think someone else linked this but seems important, yes

ah crap it was the author koe lol

its hard to read the poster when I mentioned due to the color schemes on this terminal

*when Im mentioned

just assumed it was you, nvm, but ukoehb ^

thanks vtnerd
