En Talk:Requirements

English page vs German page

Hi. I see the German page is different from the English one, e.g. it talks about processor details, more RAM, and web browsers. The French one is more similar to the German one, but differs in some details. Could somebody synchronize/update some of the versions, or point to the best ones to translate from, please? Thank you. --Ktplulo 23:02, 3. Jul 2011 (CEST)

The real requirements

• For the index of current size (2-3 billion of URLs, 500-600 millions of words) to work properly, with the current number of active peers (250-400; whatever “active” means) an “active” YaCy peer should hold 20-30 millions of URLs, and a few millions of words.
• I’ve heard that a million of URLs seems to correlate with a gigabyte of RAM. Not sure how true that is. Also, the German article says something changes with index growth. The German article has been there for over 2 years, haven’t the requirements changed at all?
• The minimal requirements for the network of the current size to work with the index of the current size would then be too big for a home computer.
• If you say those requirements are what is necessary to run a YaCy peer (senior or any), most people interested won't join the YaCy network. So the network will not grow, but as index will, the requirements will only become bigger.
• If all or most of the “passive” or the “potential” peers, whatever that means, become “active” peers, the needed local index size will become significantly smaller (ideally making the computers of most users interested sufficient, but of many in any case). Count in the people who refused to try YaCy because they read it needs 25 GB.

I'm pretty sure you don't need 1GB RAM per 1 million links. As far as I know, yacy is designed to run properly on low-end computers - You don't need a supercomputer.

The meaning of active, passive and potential peers; an active peer is online and reachable through port forwarding, a passive peer is offline, and a potential peer is online, but behind a firewall and cannot be reached through ports.

Maybe the 1GB per 1 million was not about RAM, but http://www.yacy-forum.org/viewtopic.php?f=12&t=645 --Ktplulo 10:02, 26. Feb. 2012 (CET)

Thanks, the info about active, passive and potential peers needs to be added to the FAQ. --Ktplulo 20:19, 27. Feb. 2012 (CET)

/Network.html shows that:

• Active peers can be Senior or Principal; some Senior peers have “Contact: Passive”, some don’t have DHT Receive;
• All Passive peers are Senior.
• All Potential peers are Junior.

It doesn’t matter much that YaCy runs well with tens of millions of entries in its index on any computer, if it takes weeks or even months to receive those millions (which is apparently related neither to the computer’s speed, nor to the network connection). :( E.g. this message in a 2009 discussion mentioned in the FAQ says a peer gathered 13 M links in 6 weeks, and that (from a machine translation) “YaCy can currently collect a huge amount of data a lot faster than maintaining the resulting index.”. --Ktplulo 20:28, 27.
