+# How to benchmark computer performance
+
+## Requirements
+
+- Linux computer running Debian-based operating system
+
+## Caveats
+
+- When copy/pasting commands that start with `$`, strip out `$` as this character is not part of the command
+
+## Guide
+
+### Step 1: install dependencies
+
+```console
+$ sudo apt update
+
+$ sudo apt install -y bc curl openssl sysbench
+```
+
+### Step 2: download (and optionally verify) [benchmark.sh](./benchmark.sh) ([PGP signature](./benchmark.sh.asc), [PGP public key](https://sunknudsen.com/sunknudsen.asc))
+
+```shell
+curl --fail --output $HOME/benchmark.sh https://raw.githubusercontent.com/sunknudsen/privacy-guides/master/how-to-self-host-hardened-bitcoin-node/misc/how-to-benchmark-computer-for-bitcoin-computation/benchmark.sh
+chmod +x $HOME/benchmark.sh
+```
+
+### Step 3: run benchmark.sh
+
+> Heads-up: benchmark should take between 5 and 10 minutes, but can take longer on slower hardware.
+
+```console
+$ $HOME/benchmark.sh
+Initiating…
+Do you confirm model of disk on which “/home/sun/test-7d82aa” is stored is “Samsung SSD 970 EVO Plus 1TB” (y or n)?
+y
+Benchmarking SHA256 computing…
+Benchmarking CPU…
+Benchmarking memory…
+Preparing sysbench fileio dataset…
+Benchmarking disk using 16K block size…
+Benchmarking disk using 1M block size…
+
+Result:
+
+openssl value in thousands of bytes processed per second
+sysbench_cpu value in events per second
+sysbench_memory, sysbench_disk_prepare and sysbench_disk_rndrw values in MiB per second
+score value in times faster than Raspberry Pi 4 4GB with Samsung T7 Touch SSD 1TB

+
+Go to https://github.com/sunknudsen/privacy-guides/discussions/220 and publish JSON code block as comment.
