  • I don’t know about other homeserver implementations but synapse kinda sucks. It used to randomly eat 100% of 1 or 2 CPU cores (including the database) until I tracked it down to 3 rooms having a messed up state which caused costly SQL queries. I removed the rooms from my server (using a third party admin panel because there’s no proper admin GUI built in, the documentation just mentions curl commands to hit the admin API, with placeholders to manually replace). It has been fine since I did it, but I’m the only user on my server. And I expect other issues to come up at any time…

    It also eats a lot of storage, mostly the database. It grew very large quickly, but it’s more stable now




  • There are a few things I don’t like about this scoring system :

    • Why is there a “Top Provider Content Share” metric if its gonna score the same as the “Top Provider User Share” every time ?
    • Why is the Top Provider Content Share not higher than the user share ? For instance, emails usually have at least one sender and one recipient, making it twice as likely that at least one of them is using gmail. If an email has 10 recipients across 10 different providers, each provider has a copy of the data
    • Why is ease of hosting a mail server rated so well ? How is “leveraging email hosting services” decentralized in any way ?
    • Why are we using a random repo created a few hours ago by a random github user as a reference ?








  • Your ISP might make you go through another layer of NAT. Can you find the WAN IP address of your router and compare it to your public IP address from a website such as ipinfo.io ?

    If they do not match, you’re probably out of luck and will need to forward your port from an actually public IP in order to achieve what you want

    More details : CGNAT (Carrier Grade Network Address Translation) is basically a second router between your router and the public internet. This second router is configured in the same way as your personal one, the main difference being that your ISP fully manages it. From the viewpoint of this second router, your WAN IP is a private IP, and you share one actual public IP with several other customers (the same way all devices on you LAN share one single WAN IP)

    Performing port forwarding from the public internet to your LAN, when behind a CGNAT, would require you to be able to configure a forwarding rule in the ISP’s NAT, which you usually cannot do.
