Most apps use a much smaller buffer to keep latency low, so I though it was a reasonable size. I didn't want to waste too much non-swappable memory. If you decide to raise the 256K limit, please let me know, because I have to lower the .periods_max value (the s-g list stays in one page, so if the buffer is too big, the s-g list may not fit in one page). -- Giuliano. ------------------------------------------------------------------------- Take Surveys.
