Improving Input / output jitter performance?

[Zlartibartfast]

Any I/O tasks your computer performs can momentarily increase jitter. Moving your mouse or typing on the keyboard can do it, and running additional processes (apps/plugins) can contribute.

Main thing is - are you hearing distortion or artifacts? Is the session hanging up or dropping out?

If your answer is "no" to either question, then you don't have a problem. If you answer "yes", then it's time to look closely at all the factors.
