How fast is a Lisk transaction?

Excuse me, could you please elaborate on the speed of a Lisk transaction? I'm curious to know how quickly a transaction can be processed and confirmed on the Lisk blockchain. Is there a specific time frame or does it vary depending on factors such as network congestion or the complexity of the transaction? Understanding this information would be valuable in assessing the efficiency and usability of the Lisk platform for my cryptocurrency needs. Thank you for your time and expertise.
