Slow contacts but scared to hack

[Livebetter36]

My exchange contacts contains 6000 contacts. The base blur apps are painfully slow accessing contacts. It can take 20 seconds after I FINISH typing a name. My BB was instantaneous as I typed. I am trying Touchdown right now and it is fast. WAASAP with the blur app. It almost seems lke it is querying the exchange server as if the contacts aren't really on the X. Any ideas?
