+In these notes we describe how to benchmark and profile genesis with a
+`cardano-node` downloading blocks from mainnet. We wrote three scripts to
+help with this task:
+
+* provision.sh
+    * installs nix, clones repositories, and configures a cabal project to
+      use these repositories.
+    * Downloads a db-mainnet snapshot to save setup time.
+    * Installs system dependencies via nix and builds the cardano-node and
+      the immdb-server.
+* run-server-node.sh:
+  Runs the immdb-server and launches toxiproxy so the server is reachable
+  through multiple addresses that can be supplied as different peers for the
+  syncing node to connect to. The amount of addresses is taken as an input
+  parameter to the script.
+* run-syncing-node.sh
+    * Resets the state of the chain db so synchronization starts at a
+      designated slot in the past.
+    * Runs the syncing node until the tip of the volatile db reaches or is
+      newer than a designated slot.
+    * At the end prints how long it took to run the syncing node and the memory
+      usage report from the GHC runtime produced with +RTS -s
+
+provision.sh must run first to install system dependencies and tooling. Then
+the server and its proxies can be started with run-server-node.sh. And finally
+run-syncing-node.hs can be started in another terminal.
+
+All three scripts build Haskell libraries and binaries in the normal way, but
+with a profiling-enabled GHC. This makes it easy to reuse the setup to build
+with profiling enabled.
+
+We have used the scripts successfully in a t3.2xlarge machine in aws with 400
+GB of storage and ubuntu installed.
+
+### How to start the server
+
+The following command runs the server and configures 30 proxy addresses to
+connect to it.
+```
+$ ./run-server-node.sh 30
+```
+
+### How to sync with genesis disabled
+
+The following command runs the syncing node which will connect to a single peer
+and synchronize using Praos.
+```
+$ ./run-syncing-node.sh 1
+```
+
+The following command will connect to 30 peers and will synchronize using Praos.
+```
+$ ./run-syncing-node.sh 30
+```
+
+### How to sync with genesis enabled
+
+The following command runs the syncing node which will connect to two peers and
+synchronize using Genesis. Genesis can also synchronize with only 1 peer, but
+it is slower because the implementation is not optimized for that case.
+```
+$ ENABLE_GENESIS=1 ./run-syncing-node.sh 2
+```
+
+Using 30 peers should produce little overhead when compared to only 2 peers.
+```
+$ ENABLE_GENESIS=1 ./run-syncing-node.sh 30
+```
+
+### How to tweak the range of slots to sync
+
+By default, the script will synchronize 50000 slots starting at slot 100007913.
+To synchronize 155000 slots instead, the environment variable `NUM_SLOTS` can
+be used.
+```
+$ NUM_SLOTS=155000 ENABLE_GENESIS=1 ./run-syncing-node.sh 30
+```
+
+The initial slot of the range is harder to change because the startup of the
+node is optimized with a snapshot of the ledger at slot 100007913. Generating a
+snapshot for a different slot would make it possible to start the range from
+it. But at the price of deleting the current chaindb, one can start syncing
+from slot 0 with,
+
+```
+# WARNING: deletes the chaindb from the local storage
+$ SYNC_FROM_0=1 NUM_SLOTS=155000 ./run-syncing-node.sh 1
+```
+
+### How to connect to other nodes than toxiproxy
+
+The following uses a custom topology file, instead of generating one that
+connects to toxiproxy.
+
+```
+$ TOPOLOGY=toplogy.json ./run-syncing-node.sh 1
+```
+
+For instance,
+```
+$ cat topology.json
+{"publicRoots": []
+, "localRoots":
+  [{ "accessPoints":
+     [ {"address": "34.216.201.242", "port": 3001}
+     , {"address": "3.77.115.8", "port": 3001}
+     ]
+   , "advertise": false
+   , "hotValency": 2
+   , "trustable": true
+   }]
+}
+```
+
+### How to collect the eventlog of the syncing node
+
+The following command collects the eventlog.
+```
+$ CARDANO_NODE_RTS_FLAGS=-ls ENABLE_GENESIS=1 ./run-syncing-node.sh 30
+```
+
+This produces a file `cardano-node/cardano-node.eventlog` that can be fed to
+`ghc-events-analyze` to observe the CPU consumption per thread.
+
+### How to produce tracing with full detail
+
+The following command enables tracing with full detail.
+```
+$ ENABLE_FULL_TRACING=1 ENABLE_GENESIS=1 ./run-syncing-node.sh 30
+```
