Optimize performance for SSD (NVMe) on Linux

SSD_optimize_linux.sh

sudo cp /etc/fstab /etc/fstab.bak

# Eschewing Access Times
sudo nano /etc/fstab
# add this options, make sure they’re all separated by commas and no spaces.
noatime,nodiratime
# example: UUID=uuid_number  /  ext4  defaults,noatime,discard,errors=remount-ro  0  1A

# TRIM Fit
discard

# Add to kernel boot parameters
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset scsi_mod.use_blk_mq=1"
sudo update-grub2

# Benchmark
sudo hdparm -tT --direct /dev/nvme0n1

you can add barrier=0 to fstab parameters, with docker applications increase substantially the io and reduce latency
