In a studio they should use a very good mixer to provide zero monitoring latency, with what ever effects you want. How much latency the machine has got doesn't matter at all, since this is compensated by the DAW. Virtual instruments are something else. I'm aware that some expect lower latency from samples, than the original instruments have got ;). Don't get me wrong, I prefer most possible latency as well, but the Wiki isn't about latency, it's about professional audio and it makes no sense to continue such a fruitless discussion. The Wiki is partial outdated, conflicting in hints to e.g. the AUR linux-rt config and hints how to manually edit a kernel RT config. Etc. pp. ... At the moment I'm working on an Ardour project using a RME HDSPe AIO, 44.1 KHz (I couldn't chose 48 KHz for this project), 128 frames, 2 periods. FWIW I usually get lower latency when using a pro-sumer USB Focusrite, than when using the RME PCIe card, but it doesn't matter, since around 5.8 ms are ok. Btw. QjackCtl does report 5.8 ms, not 2.9 ms ;). In regards to latency pro-sumer not necessarily must be better than professional. There are many components that have impact on latency. Depending on what I do, I easily could go down to values between 1 ms and 5 ms, but not for advanced audio productions. If I use another mobo, I get different values.
