# EIP-1559 Performance Test Update 🔥

## TL;DR

- **22 hours** non-stop test
- **6426 blocks** processed
- **41 M** gas/block average
- More than **12 millions transactions** executed
- **2139** average transactions per block
- **95%** of blocks were at least **15M** worth of gas

All nodes kept in sync for the whole session and were able to process blocks normally.
Metrics were all quite constants (CPU, memory, block time).

## Results

- Mean gas used: `41944672`
- Sum of gas used: `269578407000`
- Max gas used: `86016000`
- Min gas used: `0`
- Median gas used: `40446000`
- Standard Deviation of gas used: `21043566`
- Variance of gas used: `442831673542887`


## Network topology

- 4 Besu nodes
- 4 Geth nodes
- 2 Nethermind nodes


## Node monitoring
During the session we monitored one `Hyperledger Besu` node.
Here are some metrics captured, time window is the whole session (22 hours).

### Block time


### CPU


### Memory


### Disk usage
