Hi community could you give me some advise which hardware is at the moment the best for mining Monero
-
qay
or what plattform is usefull
-
sech1
Ryzen 9 3900X or 5900X, depending on which one you find cheaper
-
sech1
and some 2x8GB 3600 MHz CL14 memory
-
qay
ok cool thanks

i have server with 32core and nvme disk and 50mb download but blockchain is not going fast

smth like "Synced 2434126/2540692 (95%, 106566 left, 24% of total synced, estimated 2.4 days left"

moneromooo
Ouch. This is much more than expected. Linux ?
-
Guest555556
yes

Guest555556
if do out_limit 99999 is better?
-
moneromooo
Run "top", and paste the status line, the onestarting with "%Cpu(s)".
-
moneromooo
The values might fluctuate, try to pick a representative one.
-
moneromooo
It'll connect to more peers, but usually dl speed isn't the bottleneck.

You can check with "sync_info", the "mooo" line will tell you if it's blocked on network.
-
moneromooo
That's not the right line.
-
Guest555581
no block i checked
-
Guest555581
just is very slow!
-
Guest555581
if i download blockchain as file is better?
-
moneromooo
No.
-
moneromooo
What's the "mooo" line in sync_info ?
-
Guest555581
when i did sync_info no moo line
-
moneromooo
It'll have those chars: o, ., probably m, possibly _ and /.
-
nioc
Doesn't a 32 core cpu still only use 1 core/thread to sync?
-
Guest555581
2cpu 16 x2 =32
-
moneromooo
OK, paste the whole output of sync_info to paste.debian.net and paste the url here.
-
hyc
no
-
nioc
Mine only uses 1 core
-
moneromooo
Transaction verification is somewhat multithreaded. PoW verification is totally multithreaded.
-
moneromooo
Which might be counterproductive depending on your cache but hey,

Well, there a clear mooo line, and it shows you've downloaded lots of blocks that are waiting to be verified.
-
moneromooo
So your download speed's just fine.
-
moneromooo
Get us the %Cpu line from top.

-
moneromooo
Oh, that reminds me. Someone had asked some days ago about very slow tx construction. I think it's probably DNS lookups. If you're around, try with --no-dns and see if that helps.
-
moneromooo
Get us the <font size=+20>%Cpu</font> line from top.
-
moneromooo
It's near the top of... top. Third line for me.
-
Guest555581
no such command
-
Guest555581
maybe this "--disable-dns-checkpoints"
-
moneromooo
That line wasn't for you, sorry to be confusing.
-
Guest555581
ok
-
moneromooo
Then again, maybe that's also your problem :)
-
moneromooo
So try it, you're right.
-
moneromooo
--no-dns was for a wallet issue.
-
Guest555581
how to add for monerod
-
moneromooo
Just --disable-dns-checkpoints at the end of the command line, as you said.
-
Guest555581
ok
-
Guest555581
nothing changed

noperallels
hey can anyone here help with troubleshooting my monero node setup? Just trying to learn about it.. on my third attempt, i'm now only gaining 2% of the blockchain in the last 24 hours. currently at 87%. any idea why its taking so long? first couple tries didn't get this much downloaded before i screwed stuff up.
-
moneromooo
Is the blockchain on a spinning disk ?
-
Inge
noperallels: it is quite disk (random access) and cpu intensive
-
noperallels
the first two attempts were on 256gb microSD. this third attempt is on a 2TB HDD
-
moneromooo
I assume a spinning one. Move to a SSD then, it'll be *much* faster.
-
moneromooo
Once synced, you can move back to the HDD.
-
noperallels
it's an old CPU, but still only running 20%-30% mostly, with nothing much else running.
-
moneromooo
CPU should not be too much of a problem compared to a spinning disk.
-
moneromooo
Did you get a warning about this when monerod started ?
-
noperallels
yeah it hasn't stopped spinning in the past week since i started trying this.
-
noperallels
i don't recall.. i recall reading to expect days. the first 75% went in a day or two. but from 75-87 has now been about 3-4 days.
-
noperallels
would a 256gb microSD on USB 3.0 be good enough?
-
moneromooo
Probably not.
-
moneromooo
I'm not familiar with seek times on these.
-
noperallels
how about setting up the node on my windows laptop (with SSD) then copying the blockchain over to this linux machine with HDD and then running the node?
-
Inge
That could work
-
noperallels
i read up a bit about transferring the blockchain.. i tried taking 80GB data file and moving it from linux to windows machine but then it wouldn't load.
-
moneromooo
(assuming same endianness, which is almost certainly the case)
-
noperallels
brb
-
moneromooo
You need to copy it whlie the daemon is stopped. Might be that ?
-
noperallels
i read about the endianness requirement but that went over my head and I didn't read up on that.
-
noperallels
i might have copied while daemon running the first time, but certainly had it stopped the second time.
-
noperallels
do i need to copy only the data.mdb file?
-
moneromooo
Yes.
-
noperallels
ok, i'll give that a go.. copy this 103gb 87% file over to windows laptop and see if it can finish it off then copy it back..
-
noperallels
is it uncommon to run a full node? i looked at a map of active nodes and there's only 100 in all of canada..
-
moneromooo
It is uncommon. Most people aren't computer literate. Among the computer literate, I expect most have not dabbled in cryptocurrency. Of those who have, most have probably used only bitcoin and scams. etc etc.
-
moneromooo
A "map of active nodes" is going to be approximate at best though.
-
noperallels
lol. i used to be computer literate, 20 years ago. around the last time i used linux and IRC. now i'm just windows literate. just wanted to put this old machine to some use and get back to using linux again..
-
noperallels
will see how the node running goes.. going to leave this computer on as a home server and see if I care how much bandwidth and power it uses.
-
noperallels
thx for the input, cheers

Hyc can you take a look at this and perhaps suggest why the Monero onion explorer is not building for RockPro64?
