As sluggish as tortise, and the use of alongside with or along with. Please i need clarity.

obaseki, I'd like to help, but I don't understand the first part.
As sluggish as a tortoise - very slow. Is that what you mean?

Alongside to me implies physically next to.
Along with is more like "also."

Peter is there, alongside Mary. They are next to each other.
Peter went, along with Mary. They both went, but not necessary with each other.
