If you’re using a Linux distribution like Ubuntu or Fedora, you’re also using the Linux kernel, the core that actually makes your distribution a Linux distribution.
Each rowid represents the physical address of a row within the database and as such is the quickest way to access the row.
For example, you could take the kernel, patch it up with lots of fixes, tweak other settings, strip out everything you won’t need, and then replace your original kernel with your final product, and it will run just fine (assuming it was done right).
Drivers are the piece of software that tells your computer how to talk to the specific hardware you have installed or connected to your computer.
The drivers must be specific to the particular model of your computer or sound device, and are usually produced by the sound device or motherboard manufacturer.
When I started reading more into improving the efficiency of your code I understood what it was for but how much of an effect does Turning off screen updating will only make a difference to execution time if the code interacts with Excel in a way that causes changes to the screen content.
The grater the amount of screen changes the bigger the impact will be. Other application settings that can make a difference to execution time are Calculation and Event handling. Enable Events = False ' Code here Clean Up: On Error Resume Next Application. Calculation = xl Calculation Automatic Application. Enable Events = True Exit Sub EH: ' Do error handling Go To Clean Up End Sub Sub test Screen Updating() Dim i As Integer Dim numb Switches As Integer Dim results As String 'swap between sheets this number of times numb Switches = 1000 'keep track of time Dim start Time As Double start Time = Time 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)).
Once you have the necessary information about your sound device, you can normally obtain appropriate updated drivers specific to your hardware from the internet.
