Reducing latency on Camilladsp on a raspberry pi

[Razorhelm]

I was wondering if anyone knows what parts of the configuration are most important to reduce latency on a raspberry pi running camilladsp?

What is often recommended is to lower the chunksize, watching out for possible dropouts due to buffer underrun.
But don't trust me, I would recommend you to ask in the camilladsp tutorial thread. There are many responsive and knowledgeable people there.

Low chunk size, no resampling and no FIR filters are the key variables. What latency do you hope to achieve?

Thanks both this was exactly what I needed to know, my current system has very high latency but I only use it for music. I would like to build a second system which will play video too and I wanted to minimise latency, I don't have an exact figure in mind, just lower!
