After replacing DVD-ROOM with SSD with rack from Taobao, below are the optimization applied,

The first part reduce the unnecessary write,

  • disable atime
  • disable journaling
    /Library/LaunchDaemons/com.noatime.root.plist
1
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

    <dict>

        <key>Label</key>

        <string>com.noatime.root</string>

        <key>ProgramArguments</key>

        <array>

            <string>mount</string>

            <string>-uwo</string>

        <string>noatime</string>
12
            <string>/</string>
13
        </array>
14
        <key>RunAtLoad</key>
15
        <true/>
16
    </dict>
17
</plist>
  • less sleep
    sudo pmset -a hibernatemode 2

Move seldom used files to the original hard disk.

  • /var/log
  • /var/spool
  • ~/Music
  • ~/Movies
  • ~/Library/Application Support/MobileSync (? iDevice ???)
  • /Library/Application Support/GarageBand (1.4GB)

The cost is around HKD 200. The result is the boot time is shorter compared with my Macbook Air, subjectively.
