# PFV NFS tuning service
#
# Systemd oneshot that runs AFTER tuned.service to apply TCP buffer
# overrides. The tuned daemon's profiles (network-throughput for storage
# hosts, virtual-host for compute hosts) set 16MB TCP buffer caps which
# are too small for high-BDP NFS over LACP links. This service force-
# applies 128MB buffers after tuned has finished its configuration.
#
# Install:
#   cp pfv-nfs-tuning.service /etc/systemd/system/pfv-nfs-tuning.service
#   systemctl daemon-reload
#   systemctl enable --now pfv-nfs-tuning.service
#
# Created: 2026-07-31
# Deployed: all 7 Proxmox hosts (tsys1/3/4/5/6/7/9)
