Why is dodo slow?

Could you please elaborate on why the Dodo cryptocurrency seems to be experiencing slow transaction speeds? Is it due to a lack of scalability in its blockchain technology? Or could it be attributed to a limited network capacity, causing congestion during peak usage times? Additionally, are there any ongoing efforts by the Dodo team to address these concerns and improve the overall performance of the platform? Understanding the root causes and potential solutions to the issue would be greatly appreciated.
