By my measurements, right now our javascript code can reach 30-50-70% of Gige ethernet
bandwidth, so, no, we cannot flood the network just by making history plots.

(we cannot reach 100% because javascript code is not multithreaded,
it cycles through "request new data" and "decode javascript, make plot" states,
and the network is idle in this second state).

10gige networking is here (and 5 and 2.5 Gige, too). I would not worry too much
about saturating 1gige network interfaces.

10gige network between all computers, everything on SSD ZFS arrays, except
bulk data on ZFS HDD arrays (only for cost reasons $$$/TB).
