# 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` ![](https://i.imgur.com/gI3fxnE.png) ## Network topology - 4 Besu nodes - 4 Geth nodes - 2 Nethermind nodes ![](https://i.imgur.com/tO8AKCC.png) ## 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 ![](https://i.imgur.com/cLeFuhl.png) ### CPU ![](https://i.imgur.com/OXKhDlO.png) ### Memory ![](https://i.imgur.com/Csjy5BH.png) ### Disk usage ![](https://i.imgur.com/oYoI3Fw.png) ## Links [First block]( [Last block]( [Network Explorer]( [Eth Stats]( [CSV data](https://raw.githubusercontent.com/abdelhamidbakhta/eip1559-files/main/blocks.csv) ## Hardware specification AWS instance type: `t3.2xlarge` 8 vCPUS x86_64 32 GB RAM Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Platinum 8259CL CPU @ 2.50GHz Stepping: 7 CPU MHz: 2499.998 BogoMIPS: 4999.99 Hypervisor vendor: KVM Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 1024K L3 cache: 36608K NUMA node0 CPU(s): 0-7 BIOS Information Vendor: Amazon EC2 Version: 1.0 Release Date: 10/16/2017 Address: 0xF0000 Runtime Size: 64 kB ROM Size: 64 kB Characteristics: PCI is supported EDD is supported ACPI is supported System is a virtual machine BIOS Revision: 1.0 Handle 0x0001, DMI type 1, 27 bytes System Information Manufacturer: Amazon EC2 Product Name: t3.2xlarge Version: Not Specified Serial Number: ec27e5ec-171f-e84b-ed05-d777343b26a9 UUID: EC27E5EC-171F-E84B-ED05-D777343B26A9 Wake-up Type: Power Switch SKU Number: Not Specified Family: Not Specified Handle 0x0002, DMI type 2, 15 bytes Base Board Information Manufacturer: Amazon EC2 Product Name: Not Specified Version: Not Specified Serial Number: Not Specified Asset Tag: i-07be4923bd8ce6f3c Features: None Location In Chassis: Not Specified Chassis Handle: 0x0003 Type: Other Contained Object Handles: 0 Handle 0x0003, DMI type 3, 21 bytes Chassis Information Manufacturer: Amazon EC2 Type: Other Lock: Not Present Version: Not Specified Serial Number: Not Specified Asset Tag: Amazon EC2 Boot-up State: Safe Power Supply State: Safe Thermal State: Safe Security Status: None OEM Information: 0x00000000 Height: Unspecified Number Of Power Cords: 1 Contained Elements: 0 Handle 0x0004, DMI type 4, 42 bytes Processor Information Socket Designation: CPU 0 Type: Central Processor Family: Xeon Manufacturer: Intel(R) Corporation ID: 57 06 05 00 FF FB EB BF Signature: Type 0, Family 6, Model 85, Stepping 7 Flags: FPU (Floating-point unit on-chip) VME (Virtual mode extension) DE (Debugging extension) PSE (Page size extension) TSC (Time stamp counter) MSR (Model specific registers) PAE (Physical address extension) MCE (Machine check exception) CX8 (CMPXCHG8 instruction supported) APIC (On-chip APIC hardware supported) SEP (Fast system call) MTRR (Memory type range registers) PGE (Page global enable) MCA (Machine check architecture) CMOV (Conditional move instruction supported) PAT (Page attribute table) PSE-36 (36-bit page size extension) CLFSH (CLFLUSH instruction supported) DS (Debug store) ACPI (ACPI supported) MMX (MMX technology supported) FXSR (FXSAVE and FXSTOR instructions supported) SSE (Streaming SIMD extensions) SSE2 (Streaming SIMD extensions 2) SS (Self-snoop) HTT (Multi-threading) TM (Thermal monitor supported) PBE (Pending break enabled) Version: Intel(R) Xeon(R) Platinum 8259CL CPU @ 2.50GHz Voltage: 1.6 V External Clock: 100 MHz Max Speed: 3500 MHz Current Speed: 2500 MHz Status: Populated, Enabled Upgrade: <OUT OF SPEC> L1 Cache Handle: Not Provided L2 Cache Handle: Not Provided L3 Cache Handle: Not Provided Serial Number: Not Specified Asset Tag: Not Specified Part Number: Not Specified Core Count: 4 Core Enabled: 4 Thread Count: 8 Characteristics: 64-bit capable Multi-Core Hardware Thread Execute Protection Linux version 4.14.181-140.257.amzn2.x86_64 (mockbuild@ip-10-0-1-230) (gcc version 7.3.1 20180712 (Red Hat 7.3.1-6) (GCC)) #1 SMP Wed May 27 02:17:36 UTC 2020
