Node Setup

Setup to optimize Block Producer Performance - eg. by minimization of "missed slot leader checks"

Block Producer

# in startBlockProducingNode.sh
# run cardano-node with
# +RTS -N${CPU} -A16m --nonmoving-gc -qg -qb -RTS
cardano-node run +RTS -N${CPU} -A16m --nonmoving-gc -qg -qb -RTS ...
# this will lead to minimized "missed slot leader checks"

# in mainnet-config.json add
# "MaxConcurrencyDeadline": 4,
# "SnapshotInterval": 86400,
...
  "TurnOnLogging": true,
  "MaxConcurrencyDeadline": 4,
  "SnapshotInterval": 86400,
  "defaultBackends": [
    "KatipBK"
  ],
...

Relay Node

# in startRelayNode.sh
# run cardano-node with
cardano-node run +RTS -N2 --disable-delayed-os-memory-return -I0.3 -Iw600 -A16m -F1.5 -H2500M -T -S -RTS ...
# this will optimize memory allocation

# in mainnet-config.json add
# "MaxConcurrencyDeadline": 4,
...
  "TurnOnLogging": true,
  "MaxConcurrencyDeadline": 4,
  "defaultBackends": [
    "KatipBK"
  ],
...
