Testnet 2 Test 4

2022-02-07

For this test, we used Amazon EC2 T3 Instances with the following server characteristics:

  • Name: t3a.small
  • vCPUs: 2
  • Memory (GiB): 2.0
  • Baseline Performance/vCPU: 20%
  • CPU Credits earned/hr: 24
  • Network burst bandwidth (Gbps): 5
  • EBS burst bandwidth (Mbps): Up to 2,085

Network settings:

  • Slot duration: 10 sec

Algorithm of actions during testing:

  1. Stop creating blocks in the tested network.
  2. Generates ~80,000 transactions.
  3. Start 64 nodes.
  4. Fix the time in which all these transactions were added and accepted into blocks, i.e. executed.

Let’s analyze the line from the test results below:

Let’s check how many transactions were added and processed in the three slots.
Take 3 slots = 30 seconds.
20532959(8)-20532960(2)
(5000+5000+5000+5000+5000 + 5000+5000+1000+5000+5000 + 5000+5000+1005+5000+5000) = 67005

67005/30=2233.5 TPS.

Now let’s check the values for four slots.
If we take the 3rd slot (20532960(3)) (here we have a non-uniform distribution of transactions, since there were ~80000 in total).
(67005+5000+4758+6) = 76769

76769/40=1919.225 TPS.
