@bob @patrik @Nachbarschaft On server 404, this happens frequently. Flood subscriptions attacks and ddos occur every day. For this reason, we keep redundancy at 95%, although the server users themselves consume almost no resources.We need to repel the of spammers, ddos and bots.
We have to admit that now we have optimized the server and the load rarely rises above 10% even during the most powerful attacks

@bob @Nachbarschaft @patrik
Every small server on the network is a potential spammer or botnet member.
A villain creates accounts on thousands of servers, and then sends spam. This creates a burden.
You can have one user, but thousands of servers can be connected to it. One user will create a load equal to this thousand users.
There are few users and few servers in the matrix, so they are not faced with the problems of the XMPP, when resilience is a necessity even for small servers.

@bob @Nachbarschaft @patrik
The more small servers, the greater the load.There were cases when the number of connections on the server 404 over 10,000. XMPP is designed for these loads, so there are not some convenient matrix functions in it.

@Nachbarschaft @peter @patrik
We can not run the server Matrix,
because 4 core + 4GB is not enough for 700 users online.
On some days, there were over 3 million messages on the XMPP. +1GB database per day. Matrix server is not designed for such a load.

@Nachbarschaft @peter @patrik The strongest loads are not users.

@Nachbarschaft @peter @patrik
If any of the students does not make a Ddos attack to your server, this is not a problem .. If spammers do not send spam, this is not a problem. If your users don’t send blockchain or streaming video through your server, this is not a problem. You will not have problems if the server does not have access to the Internet.For this reason the matrix is badly
We solution this problems every day, although only 700 online users. We are holding 95% redundancy

@Nachbarschaft @peter
The server matrix supports only one core in a multi-core processor. Matrix protocol is bloated and uses resources more than 10 times more than XMPP.Consumption is 10 times more than a rough count, some say consumption is 50 or even 100 times more if an attack occurs.
WhatsApp uses XMPP with 1000 000 000 users. XMPP ready industrial standard. Matrix not ready for global use.

@Nachbarschaft @peter
Only XMPP. Matrix is experiencing problems at high loads

Today did the planned replacement certificate #letsencrypt. The server was unavailable for a few seconds.

test

@thrrgilag @Goffi Developing an XMPP-compatible solution, you get a users network XMPP. There are many social networks, but there is one social network in XMPP.

In addition, XMPP is an extensible real-time protocol. Servers are great for high loads. You may be surprised, but XMPP uses Google WhatsApp and Facebook

@ojbr ejabberd + postgresql

@Muto We can not recommend pix-art because it advertises a blaber server. In the list of alternative servers, the server 404 is not even visible, The count goes from the server of the blaber, and it seems that the others before this server do not exist.The code base Conversations and Pix-art are almost the same
We will rather make a fork of a blabber, than we will recommend it

@Wolf480pl @pskosinski @BluRaf
XMPP users = Mastodon users * 10

@Wolf480pl @pskosinski @BluRaf
Assumptions do not always coincide with reality. On many XMPP servers more than one million registration, but these accounts do not even worth taking into account, but it turns out that users XMPP are billions)

@Wolf480pl @pskosinski @BluRaf
The number of users in XMPP is difficult to compute, because there are more than 10,000 servers in the federation. The largest server has 30,000 active users online. This is much more than for example in Mastodon. XMPP is the most large free federation network (Excluding e-mail)

@pskosinski 2 000 000 000 peoples. XMPP is the most popular protocol. Probably even you use it every day, not knowing about it.

@rgggn Maintenance of large the server is too expensive. I think that no one has a couple thousand dollars in his pocket.
XMPP servers can exist on donations.
