"mode='update'" should only take a long time on the initial checkout,  
or if a change happens on another branch (Buildbot only keeps one  
working copy around).

If the slowdown is due to changing branches, you may be interested in

But in that case, you may want "mode='copy'" to avoid the problem that  
Dustin describes in the last comment there.
