How to workaround network throughput limits for high traffic canisters?

[Zane]

Can I run multiple inter-canister update calls in parallel?

Depends on your requirements. Splitting a dapp (whose canisters communicate with one another) across multiple subnets means additional latency for cross-subnet (XNet) calls. On the order of 2x the latency of an ingress message (because essentially one subnet needs to induct the other’s request, handle it and certify a response; and the originating subnet needs to induct the response and handle it; and it had to certify the request before the “server” subnet could induct it). On the plus side, i…
