infra-keep-probing: yes
This is a default setting for pfSense, and many other vendors

infra-host-ttl: 900 works well with infra-keep-probing: yes

infra-cache-numhosts: 20000 or 40000 ax 88u

discard-timeout: 1900 use 3000 if you bind vpn
unwanted-reply-threshold: 5000000 leave to default on lower end system

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

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to serve expired entries can help maintain fast response times by providing cached results even when they are slightly outdated.2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.

 

[Jack-Sparr0w]

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. ;)

[Jack-Sparr0w]

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.

 

[Tech9]

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.

sorry for spoiling the mood .. but unbound or another dns resolver can have absolutely no effect on playing games .. dns only translates IP which is then cached by the operating system, both windows and linux ... games use exclusively P2P (IP2IP) connections, whether tcp or udp .. but they definitely do not use domains, it would be pure nonsense .. but if so .. as it is directly in the cache and DNS queries are zero .. if you want fast DNS responses and do not require any blocklists .. then use fixed for example 1.1.1.1 or 8.8.8.8 .. if your pages are loading slowly .. then try traceroute or dig .. but it will probably be a bad connection or the problem will be completely different ...

The so-rcvbuf setting in Unbound DNS determines the size of the socket receive buffer used for handling incoming DNS queries. Setting so-rcvbuf to 4MB (so-rcvbuf: 4m) versus 1MB (so-rcvbuf: 1m) has implications for performance and system configuration:

• 4MB (so-rcvbuf: 4m): A larger buffer helps handle traffic spikes more effectively, reducing the risk of packet loss and improving reliability during high-load scenarios. This is particularly beneficial for busy DNS servers or environments with high query volumes. However, the operating system may impose limits on how large the buffer can be set. On Linux systems, you may need to adjust net.core.rmem_max via sysctl or run Unbound with root privileges to allow larger buffer sizes.

• 1MB (so-rcvbuf: 1m): A smaller buffer is generally sufficient for less busy environments. However, during traffic surges, it may lead to dropped packets or increased latency. Some systems may not even allow this value to be fully allocated, as seen in error messages like so-rcvbuf 1048576 was not granted. Got 425984.

In practice, using so-rcvbuf: 4m is recommended for better performance and reliability, especially on high-traffic or gaming-oriented DNS setups, provided that the system is configured to support the larger buffer size.

I have been using unbound for a very long time now. seen the program from the start. my tune is better, I left room for overhead.

Is there any gaming mentioned in Unbound documentation?

Using Unbound for a long time is one thing, but you also have to understand what you are reading and for what application. TNSR software is running on x86 hardware with much larger than your RPi router resources and serving much larger than your networks. Whatever they recommend is for their specific application. You don't even need Unbound on your home router.
