We have received an answer directly from Valve:

“Decryption is an active process on the user’s machine. The time it takes to decrypt the game has a large degree of variability depending on the total size of the game, the customer’s CPU capabilities, and the customer’s disk I/O speed. Customers with top-of-the line systems will likely be able to start the game within a few minutes. Customers with older/slower machines will take longer.”
