I'll play the devil's advocate here. Even though it may not be noticeable
for everyday use what about generating a report from a large database like
the ones that always seem to be on lost/stolen laptops? It seems we are
always hearing about 100's of thousands of compromised identities when a
laptop is stolen. If these are stored in a SQL database then a measurable
slowdown may indeed be perceptible when generating reports from that
database. Knowing in advance what the actual slowdown is would allow someone
contemplating using bitlocker to compare it to other solutions.
