I tend to load AVD through snapshot which can be setup in the AVD Manager > Choose AVD > Details... > Checking Emulator Options: Snapshot, and then to run the AVD, Select AVD in AVD Manager > Start... > Select Save To Snapshot and Launch from Snapshot. The first time, ensure that save to snapshot is chosen, as no snapshot exists to launch. The next time onwards choose launch from snapshot.

Slightly apprehensive to suggest this as well, but I have noticed a peculiar behavior when loading and running AVD. When I have the laptop battery being charged on my Lenovo laptop - 64 bit Windows 7, 4GB, 2.5GHz machine, the emulator loads and runs slightly faster and also lags less. I wonder if it is the configuration on my laptop to slow down high computational processes. Would be nice to know if someone else has noticed this behavior? Unplug the charger when the AVD is loaded and see if the AVD slows down.
