There have been reports that modifying the assembly_valheim.dll file to increase m_dataPerSec has resolved some of the issues caused by the server limiting the outbound bytes/seconds to each client.
Please see this Reddit thread for further information:

It appears that this will not solve the issue for people with DSL but it is worth investigation.
