Valheim provides all of the tools needed for players to set up their own servers and share the experience. However, many people have complained about server slowness on message boards, which significantly reduces the thrill of gaming:

I got mine from a site that I won’t disclose just now, and we’ve created a medium-sized foundation with it. We are presently experiencing MAJOR server-side slowness due to nothing incredibly large and massive. Chests will not open, opponents will run in place, etc.

According to experienced players, the problem arises because the server limits each client’s outbound bytes/seconds.

How can I avoid lag on the Valheim dedicated server?

  1. The hosting server should be shut down.
  2. All game files may be found under SteamLibrarysteamappscommonValheimvalheim_DataManaged
  3. This dnSpy utility is available for download.
  4. In valheim Data or valheim server Data, open the assembly valheim.dll file.
  5. Inside the assembly, look for ZDOMan.
  6. Locate m dataPerSec, right-click it, select Edit class, and adjust the value to something higher. Speeds might be significantly improved by adding a 0 to the equation.
  7. In the class editing window’s lower right corner, click Compile.
  8. Choose File > Save Module (rather than CTRL+S).
  9. Start playing after restarting the server.
  10. In the F2 menu, see if the speeds have increased.

According to players, raising the server send speed restrictions from 64kb/s to 94kb/s improved matters.

They also suggest increasing the transmit limits on the client’s end.

However, it is critical to alter the server’s limitations first before attempting a modification on the client’s side. In addition, the Managed file must be downloaded on its whole.

This is merely a workaround, as the players have pointed out. On the other hand, the game’s developers have noticed the flaws and are likely to work on a reliable patch for future updates.
