How long does it take to bridge from Scroll to Ethereum?

Can you please clarify the specific time frame for bridging assets from Scroll to Ethereum? I'm interested in understanding the average duration it takes for this process to complete, as well as any potential factors that might affect the timing, such as network congestion or the size of the transaction. Additionally, I'd like to know if there are any best practices or recommendations for optimizing the bridging process to minimize the wait time.
