11:11:04 <lumberjack123> Has anybody here seen something like this? ^
13:23:19 <ndorf> or -- hear me out here -- just use monero
14:29:40 <Rucknium[m]> lumberjack123: Yes. I run this webapp: https://fusionstats.redteam.cash/
14:55:35 <[Syntax]> My wallet is syncing super slow.. like 18 blocks per minute..
14:56:03 <[Syntax]> says 8 days to sync 300k blocks..
14:56:24 <moneromooo> Is the blockchain on a spinning HDD ?
14:56:27 <[Syntax]> any ideas?
14:56:33 <[Syntax]> yes
14:56:45 <moneromooo> Are you on Windows ?
14:56:59 <[Syntax]> the wallet is..
14:57:18 <moneromooo> Is monerod running on Windows ?
14:57:21 <[Syntax]> yes
14:57:30 <moneromooo> Then you can:
14:57:34 <moneromooo> - exit monerod
14:57:50 <moneromooo> - copy the blockchain (data.mdb) to another file for backup
14:58:02 <moneromooo> - restart monerod with this extra parameter: --db-sync-mode fast:async:1000000
14:58:12 <moneromooo> If all goes well, it'll be faster.
14:58:43 <moneromooo> However, windows is a bit shite and the chain can become corrupt if something goes wrong with these settings. If it does, copy the backup back.
14:58:56 <hyc> ^ windows is particularly unreliable though. any crash will mean starting over from scratch
14:59:22 <moneromooo> Alternatively, use a SSD if you have one.
14:59:58 <[Syntax]> Do you think its slow because the old file is corrupted? previous sync was interrupted
15:00:06 <[Syntax]> and then it became noticably slower
15:00:07 <moneromooo> When you start monerod, it's supposed to tell you it'll be slow if it sees a spinning HDD. Does it do so ? Might not have been implemented on windows...
15:00:32 <moneromooo> It's slow because lots of seeks and writes, and HDDs are bad at that.
15:01:48 <[Syntax]> Im copying the blockchain to an SSD, going to see if that helps any.
15:02:09 <[Syntax]> 35 min to copy it.. :/
15:02:27 <[Syntax]> ahh its going down.. 16min
15:02:28 <moneromooo> Make sure monerod is down when you do it.
15:06:26 <gingeropolous> "2022-03-25 15:04:12.864 I Synced 2576400/2587413 (99%, 11013 left, 34% of total synced, estimated 1.7 hours left)
15:06:26 <gingeropolous> "
15:06:37 <gingeropolous> those percentages make my brain hurt
15:06:58 <moneromooo> How much ? 20% hurt ? 40% hurt ? more ?
15:08:19 <fluffypony> gingeropolous: we can make it like the Windows file copy dialog instead
15:08:33 <fluffypony> https://imgs.xkcd.com/comics/estimation.png
15:14:03 <gingeropolous> lulz
15:15:57 <gingeropolous> the last % must be the size. 
15:16:16 <gingeropolous> thats what im going with. its probably already on the stack exchange or some faq somewhere
15:16:37 <moneromooo> The first % is how much of the chain you've synced.
15:16:39 <ndorf> it's 99% of the total blockchain, 34% of what was missing when you started monerod
15:16:56 <moneromooo> The second % is how much of the remaining chain you synced from when you started monerod last.
15:17:22 <moneromooo> But yes, it's confusing until you're told what it is :D
15:17:32 <ndorf> maybe the word 'total' shouldn't be there
15:17:37 <ndorf> dunno.
15:17:50 <moneromooo> "incremental" maybe ?
15:17:56 <ndorf> something like that, yeah
15:17:59 <moneromooo> That would be also confusing, but maybe less so.
15:18:14 <ndorf> yeah, there's probably a better way to present it
15:18:21 <ndorf> not enough coffee to think of it at the moment
15:18:46 <[Syntax]> ok copy complete and bat redirected to new location..
15:18:49 <gingeropolous> excellent. i'll make a PR to include "drink more coffee to understand these percentages" in that status
15:18:50 <[Syntax]> give this another try
15:19:12 <ndorf> [Syntax]: should be much, much faster with SSD (assuming you have decent bandwidth to begin with)
15:19:31 <ndorf> not only syncing but making new transactions will be much faster, as well
15:20:52 <[Syntax]> wtf, now its like 40 blocks a second..
15:21:23 <ndorf> yes
15:21:29 <[Syntax]> was 1/3 of a block per second before..
15:21:35 <ndorf> it might get even faster once you get more peers :)
15:21:40 <[Syntax]> not sure why it would be that big a difference
15:21:55 <ndorf> because there are a lot of random writes.
15:21:57 <moneromooo> < moneromooo> It's slow because lots of seeks and writes, and HDDs are bad at that.
15:22:01 <ndorf> ^ that.
15:22:18 <gingeropolous> solid state drive is that much faster than a little tiny magnetic head on a mechanical arm finding specific locations on a spinning disc
15:22:34 <[Syntax]> is it not writing the file sequentially? is it updating blocks previously written to the blockchain?
15:22:48 <[Syntax]> dont really understand what its doing, I thought it was just appending transactions
15:23:00 <moneromooo> It is a database, not a sequential tape archive or so.
15:23:19 <moneromooo> Things inside are sorted, not necessarily by height.
15:23:55 <gingeropolous> well i've made it past bloc ~2450000 on my sync, so i dunno about https://github.com/monero-project/monero/issues/8194
15:29:13 <[Syntax]> Well says 2 hours left to sync, instead of 8 days..
15:32:49 <ndorf> sounds about right
16:02:29 <selsta> gingeropolous: I also wasn't able to reproduce.
16:03:09 <moneromooo> You have the same CPU or motherboard ?
16:03:39 <selsta> No, that's why I why I'm waiting for this person to test with a different CPU so that we can check if it is related.
16:03:40 <moneromooo> I'd ask them to run the randomx test program, if it still exists.
16:07:17 <selsta> ok. I left a comment
18:26:36 <gingeropolous> ima try syncing on this potato: model name      : Intel(R) Core(TM)2 Duo CPU     T8100  @ 2.10GHz
18:28:49 <hyc> I can prob fire up my old qx9300 if we need an old CPU
18:29:20 <hyc> but I think techwise it's the same level as that T8100
18:34:14 <fluffypony> try get it going on a 1ghz Pentium IV
18:35:18 <gingeropolous> i shouldn't have sold my gallatin
