When watching videos in Solaris, I notice a lot of playback jitter. Under Linux, video playback is much smoother. Since XVideo in Solaris on NVidia supports vsync, I figured it might be a scheduling issue.
This morning, I was looking into configuring a custom kernel for my Linux laptop, when I noticed that there are specific tick rate settings also mentioning multimedia playback (usually 250 or 300hz). Now checking options for Solaris, which runs on my desktop, I found out that its only 100hz. Supposedly a slower tick rate results in coarser scheduling granularity, contraproductive for multimedia. There's hires_tick, which however immediately boosts the rate to 1khz. What sort of performance impact would the 1khz setting have on regular operation (apart from screwing up power management I'd guess)? It wouldn't suddenly result in smaller time slices, would it? Is there a way to set an arbitrary value?
