Roll your own - on a virtual server.


Greetings all,

I recently read of the optimization benefits of compiling the kernel vs the kernel provided in a pre-compiled distro. As I understand it, doing this will optimize the output more specifically around the system's architecture.

My curiosity is the affect this will have when performed inside a virtual environment (eg, a VMware virtual machine), which is abstracted from the hardware. Would the optimization be negated or even harmful to the performance of the kernel when you later adjust the VM by adding/subtracting CPU's or allocating more/less memory?

In advance, thank you for your expertise.

If you were building a kernel for use in a VM, you would build it for the virtual hardware presented to the guest operating system, not the hardware your computer actually has.

As for what type of real-world benefit this would give you, I couldn't really say. My gut feeling is that the work put into it would not be worth the small improvement you might get; especially if you are considering changing the emulated hardware down the line (though adding more memory wouldn't be a problem).
