1  Bitcoin / Development & Technical Discussion / Re: VanitySearch (Yet another address prefix finder) on: August 25, 2020, 12:44:51 PM
Okay, I've ran some tests and noticed that:
My antivirus is acting up whenever I'm using vanitysearch, it's not detecting anything but consuming a lot of resources.
Much higher than what Vanitysearch is using; so I've included it to my AV's "exceptions list".
And it worked!

What's the best way of maximizing the generation speed ? Is there any good config out there?
Somehow, vanitysearch isn't using all of the cores or even processing power when using that command, there should be something wrong.

Whatever the reason is, I've tried to use 1 thread and it resulted with a slightly slower rate (just about -10%).
So, try to run 3-4 instances of Vanitysearch running with the same command but pointing to different output files.

Creating batch files is a good shortcut to do this, eg.:
instance1.bat
Code:
vanitysearch -t 1 -o output1.txt 1*
instance2.bat
Code:
vanitysearch -t 1 -o output2.txt 1*
instance3.bat
Code:
vanitysearch -t 1 -o output3.txt 1*
...And so forth

Each instance will be slower than a solo instance but overall number of generated addresses and keys could be higher.

Yeah, I already thought about that, to use different instances of Vanity

I don't run an antivirus though. I'm pretty sure there's an issue with cpu thread selections on some CPUs and that's what I'm encountering atm.

I also don't run an AV because I don't need one, I tried with Defender off aswell and same result. Nothing is using my processor except vanity.

Won't solve the issue.
Don't know but your previous speed doesn't sound right for an old i3 CPU from 2012 (third-gen maybe) when searching for '1*'.
You'll likely get 1000-2000 per update of "Found" at best (based from my PC w/ i3-4130 procie).

Other than the additional -c which is unnecessary for a wildcard prefix, I can't find any issues with the command you're using.
If you previously used an older version with faster result, then downgrade to that.

The weird thing is, your processor can search for Million keys per second, while it can only "no-prefix-search" random address & key pair @ thousands per second.
Perhaps it's not meant for that use-case.


I swear to god it used to find 20.000 addresses per second.
As soon as I started the software, in the first second it showed [Found 21529], as example. The next second was [Found 37176], as example. That's nearly 20k per second.

I checked the text file and it indeed contained almost 40k PUBLIC addresses only. NOT including the PRIV KEYs and other Lines. I use Notepad++ and can count.
Yes, it did 20k per second.

The weird thing is that it does not do that anymore, and it only does around 600 Addresses per second with THE SAME settings.

This is why I'm asking, I haven't done any OS updates since then. One day it just stopped finding 20k per second, and it did only around 600.


I used VanitySearch 1.18 but I also tried other versions. Same result - around 600 addresses per second, not 20k as it used to do a while back.
It's weird.


EDIT:

I have an AMD GPU (RX480 @ 4GB). From what I know, VanitySearch doesn't support OpenCL or any way of using AMD GPUs.

What's the best way of maximizing the generation speed ? Is there any good config out there?

-snip-
start %USERPROFILE%\Desktop\VanitySearch.exe -c -o output.txt 1*

Why is it only doing 600 adresses /sec instead of 21000 per /sec as it used?
If it's not a hardware issue, my guess is: Vanityseach might be struggling to write on that output file due to its current size.

Have you been using the same 'output.txt' file since the start?
If yes, try to use a new text file like "-o output2.txt" and see if it will speed-up.

Won't solve the issue.

Tried:
-other output file names .txt that are even empty / fresh files
-restarting the system
-change thread numbers (will do the same no matter what I do)
-set different priority on the process in task manager (normal/high/realtime - makes no difference)
-run as administrator and so on
-Changed file locations from desktop to other partitions / folders. Won't solve


Don't know what to do. The CPU is in good standing / temps


Won't solve it no matter what I do.

Also, might the "1*" be the problem? I don't necessarily want it to generate prefixed addresses.
I want it to generate any random addresses, no matter the prefix.
Is 1* the only way of doing that?

Can someone help me with a small issue..

I have an old i3 2012 CPU, that is currently only generating around 650 addresses /sec with 4 threads.





The thing is, more than a week ago it used to do around 21000 addresses /sec with the same 4 threads.

Why am I only able to generate 600 addresses /sec now? It used to do much more...

This is the current config I've set and not changed since:

start %USERPROFILE%\Desktop\VanitySearch.exe -c -o output.txt 1*


Why is it only doing 600 adresses /sec instead of 21000 per /sec as it used?

I don't get it.
