If the users can still do anything at all, only very slowly and/or
throughput dies off, this type of thing can be (and has been for me
repeatedly in the past) problems with compression.
If so, what happens is that the connected devices aren't properly handling
compression, and a packet will, for example, get sent compressed when the
other side is expecting uncompressed. This causes resent packets and
throughput goes to hell.
You can easily test it by disabling compression on your end and seeing if
things improve.
