 I'm still of the opinion that the problem is in the CPU usage of the
monitoring program -- leaving very little CPU for a browser running on the
same R-Pi to be able to /render/ updates, whereas a remote connection
browser will be unencumbered and only limited by the HTTP data transfer
(which will be about the same for remote and local browsers).

 So -- I'd consider noting the %CPU column and the associated
process/command... A partial grab (from a Debian install running in
VirtualBox -- USE FIXED PITCH FONT TO VIEW):
