You should try and identify the bottleneck. To do so, I use "perf top".
This profiling tools works on recent Linux with relatively no overhead
on the pipeline. Identify the functions that have highest cost and track
down where this function is called from. This should tell you. My first
guess would be audio re-sampling.
