Issue - FeatureBase atime issue on MacOS

Cause

atime updates can significantly reduce FeatureBase performance due to frequent access.

Solution

Use noatime on the FeatureBase data directory mount point.

Open a CLI then create a new bash script:

  #!/bin/bash

  DATA_DIR="/opt/molecula/featurebase"

  PARTITION=$(df $DATA_DIR | awk 'NR==2 { print $1; exit }')

  MOUNT_POINT=$(df $DATA_DIR | awk 'NR==2 { print $9; exit }')

  MOUNT_OPTIONS=$(mount | grep -w $PARTITION)

  if [[ "$MOUNT_OPTIONS" == *noatime* ]]; then
      echo "noatime is already enabled"
  else
      echo "noatime should be enabled for the best performance; to mount with noatime:"
      echo "    mount -vuwo noatime $MOUNT_POINT"
  fi

Run the script.
