bench-run.sh: identical test shape everywhere (4k rand rw, 1M seq rw, direct IO, grep-able BENCH| lines) - runs in guests, LXCs, containers. install-bench.sh for Debian guests/LXCs; Dockerfile for registry image; lxc-bench-setup.sh stands up the host-side bench LXC (proxmox = no docker). Ticket: https://projects.knownelement.com/issues/709

# bench-run.sh — standardized fleet benchmark (fio + iperf3). [#709]
|
|
# Same tool, same shape, everywhere: Proxmox LXCs, guests, containers.
|
|
# Non-destructive: fio writes only its own files under BENCH_DIR.
|
|
#
|
|
# Usage:
|
|
# BENCH_DIR=/path bench-run.sh # storage bench on /path (default /var/tmp)
|
|
# IPERF_SERVER=host bench-run.sh # + network test to that iperf3 server
|
|
# bench-run.sh --server # run as iperf3 server (one shot)
|
|
# Output: one "BENCH|key|value" line per metric (grep-friendly), plus meta.
