The CA client has to use a separate TCP connection to the server for
each priority, so internally the server groups them by connection and
hence by priority.

For experimental purposes the caget and camonitor programs can be
configured to use a particular priority (-p <prio> where <prio> is 0-99
with 0 as the default & lowest priority). I would suggest setting up one
camonitor of your waveform records with default priority and a second
one with higher priority on the faster channels. If this resolves the
stuttering it tells you that it's probably worth exploring this approach
further.

HTH,
