 ## Overview
 
-node_bench is a reproducible benchmark for Linux nodes (VPS / Bare Metal / Cloud). It exercises CPU with sysbench, memory with STREAM when `stream` is available, and disk with fio using direct I/O, fixed profiles, and JSON output. It prints commands to the console, logs everything, and fails fast with clear reasons (permissions, missing directory, insufficient disk space). The maintained script is hosted at [https://storage-for-testing.erpc.global/tools/node_bench.sh](https://storage-for-testing.erpc.global/tools/node_bench.sh).
+node_bench is a reproducible benchmark for Linux nodes (VPS / Bare Metal / Cloud). It exercises CPU with sysbench, memory with STREAM (auto-installs by default; use `--allow-missing-stream` to skip), and disk with fio using direct I/O, fixed profiles, and JSON output.

 ## What it measures
 
 - CPU: `sysbench cpu` with a thread sweep (1, 2, 4, 8, 16, 32) clamped to available vCPUs; each run logs the full command.
-- Memory: STREAM (if `stream` is present or installed), raw output.
+- Memory: STREAM (auto-installs by default; falls back only with `--allow-missing-stream`), raw output.
 - Disk: `fio` direct I/O, time_based workloads with JSON output:
   - 4K randread QD1 / QD32
   - 4K randwrite QD1 / QD32
