If you've installed 32-bit Linux Mint 10 on your 4Gb+ machine, but found it slower than before, you may be seeing the effects of using a PAE kernel.
The Linux Mint 10 installer will automaticall install the PAE kernel on your machine if you have 4 or more Gb of memory in your computer. The advantage of this is that you have access to all of your memory, whereas the standard 32-bit kernel can only access up to 4Gb. The downside is that your computer may be slower than before. For some this isn't an issue, as more memory can equate to more speed. But for some where the increased memory isn't enough to make that kind of difference, switching from the PAE kernel to the standard Generic kernel can bring a faster system. With a boot loader, such as GRUB, you can also have both kernels installed, and switch between them as needed.
Here are the steps to switching kernels:
Assuming all went well, you are all set!
If you are using a proprietary video driver, you MAY need to reinstall or update it for the new kernel.
Hopefully, this will help you get the most out of your system!
Please explain to those who don't know what a PAE kernel is
I had issues (display artefacts) with the proprietary ATI fglrx (Catalyst) driver on a 64-bit machine with 4 GB memory. Switching to the generic kernel resolved these. Reinstalling the driver was necessary.
Just for the sake of information, you might include a link to an explanation about what the PAE kernel is, how it's different from the standard kernel.
