How long does it take to bridge from arbitrum to ETH?

Could you please elaborate on the time frame involved in bridging from Arbitrum to Ethereum (ETH)? I'm curious to know whether this process is instantaneous or if there's a noticeable delay. Is the bridging time consistent, or does it vary depending on network congestion or other factors? Additionally, are there any steps that users can take to minimize the waiting time for the bridging process? I'd appreciate your insights on this topic.
