Alexey from Traffic Team is here. Traffic is definitely a non-negligible part of the budget. We try to reduce it as much as possible for both lower operational expenses and better user experience. Main drivers for that improvement (besides owning our own Edge infrastructure) on the client side are:
1) Brotli (Broccoli) compression.
2) Differential updates through librsync.
3) "LANSync" a P2P sync within a broadcast domain (secured through server issued short lived TLS certs.)
That said, Desktop Client is only 1/3 of the overall Dropbox traffic -- the rest 2/3 are split between Web and API.
