I believe that this is replicable with a sample data of yours, but in case you are not able to reproduce just ask and I'll attach a sample.
add a polygon layer, with a fair big number of features and enable snapping for it.
then add another polygon layer or create a new one.
start editing the new polygon layer, you'll notice that the "capture polygon" tool is pretty slow. Depending on how big is the underlying layer it can be almost unusable.
remove the snapping for the underlying layer and editing the new polygon will work just fine
tested under trunk/1.4 under both linux and windows
