Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

(I posted this over in the k3b.org forum also, but it doesn't seem as active over there as here)
I've got k3b setup to use as much RAM as possible when burning. It only allows me to set it at 2GB, and that's it.
Unfortunately it seems to use that up pretty quickly when burning a 25GB BD-R. For example, when it gets (usually) to about 10% done of 100%, the 'software' buffer will begin to go from 100% down to 0% in just a few minutes and the burning will slow down from ~40MB/s to ~12MB/s because it's stuck with only the hardware buffer.
Once in a while at around 60% finished, the software buffer will start to rise again to 100% but within only a few seconds of it reaching 100% it will start to go down again until it's using the hardware buffer again.
Does anyone have any idea(s) what I can do to have k3b use and *keep* the software buffer up during the whole burning process? As it is, 23GB onto a BD-R takes on average ~25 minutes. If it could keep the software buffer up during the whole burn process, it could probably cut that time almost in half. I have 4GB of RAM available, so it's a shame it has to fall so quickly and get stuck using 4MB of hardware buffer.

"If it could keep the software buffer up during the whole burn process, it could probably cut that time almost in half."
Actually the limiting factor is the speed of the burner. As long as you have enough software buffer to keep ahead of the hardware buffer (and you do) then the size of the software buffer is irrelevant to the speed of the burn.
If the software buffer is underrun while burning this is a sign that your storage subsystem is not able to deliver the data to the software buffer with the necessary speed. So either reduce burning speed or use a faster storage subsystem.
