Ok, I tried a few different values - 32kb, 64kb, 512kb, 2MB and 10MB. I'm not seeing any highly noticeable change in behaviour with any setting - it wasn't a scientific test, but I seem to have about the same size hiccup with each setting. The hiccup may be slightly shorter with the 10MB setting, but barely, if it is.
