What causes latency to go up and down?
On the whole latency in my system is supposedly quite low (11 ms or thereabouts).
But sometimes, when I have been working for a while, it will suddenly rocket. I will suddenly have a situation where my whole system slows to a crawl, with up to and more than 1000 ms between hitting a key and hearing the sound. As far as I can figure out, closing other applications does not really make a difference. Sometimes, the heavy latency will be on my keyboard but not my mpd32; sometimes the other way round.
What causes these variations? has anyone else experienced them?
