Hi Guys,
I know that it is not a big help, but I have unsucessfully tried to
profile code of munin-cgi-html so I have written small quick and dirty
cgi script in python, which does everything what we want (we can
navigate through graphs, view the same as in munin, have dynamic zoom
enabled and ... have fast navigation even that we have about 400
servers). If you want, you can try.
BR,
