We use a concert setup with ambdec and self-made (C++) spatialization software on Linux, for real-time spatialization of acoustic instruments. The electric latency from mic input to loudspeaker output was in the order of 8 ms, everything at 64 frames/block and 44.1 kHz with ardour2 for mixing. It was glitch-free up to a CPU load of about 80%. In later concert using ardour3 for mixing we had to use 128 frames, leading to something like 15-20ms latency (also due to different routing).
