VM used for benchmarking:

• CPU: AMD EPYC 7763, 6 Cores
• RAM: 16GiB
• Total Swap: 512MiB

Sync Performance

• Synced 90000 blocks in 41 hours and 24 minutes.
• The database size was 28GiB.

Juno is designed to only store the diffs between each block, rather than storing the entire state for each block height. This method, combined with the use of Pebble, results in efficient use of storage resources.

VM Resources Usage During Sync

• Average CPU usage was 34.3%
• RAM usage averaged at 9%
• Swap memory usage was minimal at 0.048%

Observations: An important observation with Juno is the linear increase in RAM usage until sync is complete, a pattern not observed previously.

Load Test Performance

Load tests were conducted on Juno for various RPCs.

• Average RPC response time of 31ms
