Most popular speedup sysctl options for Proxmox. Put in /etc/sysctl.d/
###
# Proxmox or other server kernel params cheap tune and secure.
# Try it if you have heavy load on server - network or memory / disk.
# No harm assumed but keep your eyes open.
#
# @updated: 2020-02-06 - more params used, adjust some params values, more comments on params

Calculating IOPS ....
IO Performance:
--------------
NCQ - Native Cmd Queueing - SATA II - 32 cmds
TCQ - Tagged Cmd Queuing - SCSI 2 - 216 cmds possible (64 cmds supported by most disk queues)
- Reordering of cmds when requests for sectors spaced far from one another.
- attempts to reduce disk seek time and rotation latency by optimising order in which sectors are found.
