Hi,
is there a limit Pi-Hole 5.0 can handle (slowing down performance significantly, etc.) Currently I have around 4 mio domains on lists and planning to add more. So questions is there a technical limitation / advise in terms of performance, etc.?
Pihole v5.0 is very fast and doesn't store all the domains in memory (only the index as B-tree, which is much smaller) As long as you have enough disk space it should be fine. I see limitations more with the number of concurrent clients/queries than with the number of domains on the blocklist. Or as the developers say it:
An other point is: is it useful to have so many domains on the blocklist...?
Many thx for the quick answer. As of now I havent really found a suitable list with mainly 200k entries to Cover 90% or more of garbage sites to keep gravity db small. Any lists u r using and u can recommend?
What do you consider 90% garbage sites? I guess there is an infinit number of ads/tracker/malicious sites out there. Of course having 4 mio domains on blocklist will potentially cover more than "only" 200.000. But the number of domains in your blocklist is just a surrogate parameter - what really counts is having "all" garbage domains on that list that you will really visit.
I have ~300.000 on my blocklist and in the last 90 days only 1150 different domains have been blocked.
To answer which lists are really good for you, I wrote a script
The one list I benefit the most from is: https://www.github.developerdan.com/hosts/lists/ads-and-tracking-extended.txt
Usage: pihole_adlist_tool [options]
Options:
-s [total/covered/hits/unique] Set sorting order to total (total domains), covered (domains covered), hits (hits covered) or unique (covered unique domains) DESC. (Default sorting: id ASC)
I personally pay more attention to unique_domains_covered
