From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm using Bitwig (the DAW) wrt hardware, it's an i7 4770 with 8gb DDR3 RAM (which doesn't seem to be filling up) and a sata SSD.
One of the things you run into with audio production software is that in order to maintain accuracy with respect to phasing between channels, they require very accurate timing, this usually comes at the expense of very high interrupt rates and context switching and under the best of circumstances this is hardware intensive, more so with older processors that don't have single instructions for storing the entire register set or restoring the entire register set to the stack with one instruction as many modern CPUs do. So hate to say it but you may need to upgrade to something less geriatric. You might also try a real-time kernel, it might allow the application to keep things sync'd up with less hardware interrupts though it will rely more on software interrupts do do the same. Unfortunately, I have found that while I can get the performance I require on my six year old processor using a realtime kernel, it has come with a sacrifice of stability, that is to say real time on my hardware at least has not been terribly stable.
What distro? What input device are you using?
