 133 <p>Why is the Unix machine 11 – 13 times slower at getting information out of the Clearcase registry than a Windows client? Note the same does not hold true for other Clearcase registry queries (e.g. lsview takes the same amount of time on both platforms) but querying UCM stream information on the Unix system is vobdog slow! It’s not slow for projects or baselines but just streams… and activities.</p>
