 In general, if you run into issues, it may be better to run this on a linux
 box; MacOS seems to hit limits quicker in general.
-
-We can profile execution using cargo-flamegraph to learn more about how long
-we spend in each function.
-
-The main thing to do is install it:
-
-```sh
-cargo install flamegraph
-```
-
-Now, start processes running ourselves (so that we can use flamegraph on them):
-
-In one terminal (in the `backend` folder of this repo):
-
-```sh
-sudo cargo flamegraph -o telemetry_core.svg --bin telemetry_core
-```
-
-And in another:
-
-```sh
-sudo cargo flamegraph -o telemetry_shard.svg --bin telemetry_shard
-```
-
-And then, in a third terminal, we can run our general soak test against these:
-
-```sh
-SOAK_TEST_ARGS='--feeds 100 --nodes 100 --shards 4' \
-TELEMETRY_SUBMIT_HOSTS='127.0.0.1:8001' \
-TELEMETRY_FEED_HOST='127.0.0.1:8000' \
-cargo test -- soak_test --ignored --nocapture
-```
