+# Bare Metal Server Setup
+
+Use this on a fresh Linux benchmark server when running the profile-store
+benchmark directly on the host instead of through Docker.
+
+The commands below assume:
+
+* the server user can install packages,
+* the repository will be cloned under `/home/ubuntu/ZoneTree`.
+
+## Install .NET SDK
+
+```bash
+apt-get update
+
+apt-get install -y dotnet-sdk-10.0
+```
+
+## Install Docker
+
+```bash
+apt-get install -y docker.io docker-compose
+
+systemctl enable --now docker
+
+docker --version
+docker-compose --version
+```
+
+## Clone The Repository
+
+```bash
+cd /home/ubuntu
+git clone https://github.com/ZoneTree/ZoneTree.git
+cd /home/ubuntu/ZoneTree/benchmarks/profile-store
+```
+
+## Install Native Dependencies
+
+RocksDB uses the `RocksDbSharp` and `RocksDbNative` packages. On some Linux
+systems, the native loader also needs a `libdl.so` name next to the copied
+RocksDB native library.
+
+```bash
+apt-get update
+
+apt-get install -y libc6-dev libstdc++6 zlib1g libsnappy1v5 liblz4-1 libzstd1
+```
+
+## Build
+
+```bash
+dotnet build src/ProfileStore.Benchmark.csproj -c Release
+```
+
+## Fix RocksDB libdl Lookup
+
+```bash
+mkdir -p src/bin/Release/net10.0/runtimes/linux-x64/native
+
+ln -sf /lib/x86_64-linux-gnu/libdl.so.2 src/bin/Release/net10.0/runtimes/linux-x64/native/libdl.so
+```
+
+If `/lib/x86_64-linux-gnu/libdl.so.2` does not exist, find the installed
+`libdl` path and use that path in the `ln -sf` command:
+
+```bash
+find /lib /usr/lib -name 'libdl.so*' 2>/dev/null
+```
+
+## Smoke Test RocksDB
+
+```bash
+dotnet run --project src/ProfileStore.Benchmark.csproj -c Release -- --engine rocksdb --profiles 100K
+```
+
+## Run A Reference Benchmark
+
+Use the normal benchmark arguments for larger runs. For example:
+
+```bash
+dotnet run --project src/ProfileStore.Benchmark.csproj -c Release -- --engine zonetree,rocksdb --output results --data data --update-latest --timeout-seconds 120000 --profiles 100K,500K,1M,2M,5M
+```
+
+With `--update-latest`, Linux reference reports are written under:
+
+```text
+reference/linux/profiles-<count>/
+```
