Unbound Tuning for gaming

Anyway to make this faster?

use (vx) to edit unbound config file (stock settings are slow)

4 core cpu and 1 gig ram

Unbound is a DNS resolver. It doesn't effect "gaming".

 

[Jack-Sparr0w]

Its more responsive due to jacking up the stats. any idea how to push it. so yes this does affect gaming. There is even recommended settings geared for gaming with unbound.

 

[Jack-Sparr0w]

running it stock is very slow loading pages, I mean if that what you guys know of tunning unbound

 

[Jack-Sparr0w]

any ideas let me know, don't need any flak on what unbound is

Sorry, what is "it"?

There is even recommended settings geared for gaming with unbound.

Can you post a link these recommended settings. I've personally never come across a game where any marginal differences in DNS lookups were relevant. But perhaps there is some specific game where it does make a difference.

Unbound DNS tuning for gaming can involve optimizing the DNS server to reduce latency and improve response times, which can be crucial for online gaming performance. Based on the context provided, here are some relevant tuning tips:

• Disable caching in Pi-hole: To avoid redundant processing, it's recommended to turn off caching in the Pi-hole instance when using Unbound. This prevents Pi-hole from performing duplicate DNSSEC validation and caching, which can slow down the system.2
• Adjust Unbound cache settings: Tuning the Unbound cache can significantly improve performance. For example, setting cache-size=0 in the Pi-hole configuration file can help avoid conflicts with Unbound's caching mechanism.2 Additionally, configuring Unbound to serve expired entries can help maintain fast response times by providing cached results even when they are slightly outdated.2
• Optimize Unbound configuration: The Unbound configuration file can be adjusted to improve performance. For instance, setting num-threads to the number of CPU cores, increasing msg-cache-size and rrset-cache-size, and adjusting outgoing-range can all contribute to better performance.3
• Use libevent for better performance: Installing and configuring libevent can allow Unbound to handle more file descriptors efficiently, which can improve performance, especially under heavy load.3
• Increase socket buffer size: Adjusting the socket buffer size using so-rcvbuf can help handle spikes in traffic and improve reliability.3

These adjustments can help ensure that Unbound operates efficiently, providing fast and reliable DNS resolution for gaming and other applications.

Can you provide a link to the source of this information.

No link I can find from all info I grabbed. at the end of the day, Its stock tuned from the get go so it can work on any router

 

[Jack-Sparr0w]

Try my settings and see the responsiveness. You have to do math to find out what numbers should be there.

Where did the information you posted in #7 come from? It looks like nonsense generated by A.I.

I don't use Unbound. If you want to optimize Unbound for normal web browsing then that's a different matter and I think there are already many posts about that.

You should try some NTP tuning for maximum effect. Or get a job.

ntpMerlin - What is ntpMerlin?

This is a great and informative video. Thanks for sharing. a Pleasure. now get the right MTU/MRU for your LAN ISP connection and with QoS, you'll be just about as good as it can get. It's not a pipe, it's a bucket brigade. ;)

does it work with local NTP, I know sc merlin can be used but i did not know ntp merlin can be used to. If so show me how this is done

 

[dave14305]

It’s another form of placebo effect. Once any DNS query is resolved and cached (by any resolver you choose), there’s not much performance gain to be realized.

You have to do math

Your math is wrong. No Unbound settings on your end-user device will make root servers respond faster nor cached queries reach local clients faster. Once resolved and cached the address is 1ms away for Ethernet connected gaming device. And skip AI generated crap.
