midi cable lenght induced latnecy?

[ZeplinSoup <ZeplinSoup@aol.com>]

should I buy a new cable??my current cable wraps around 3 football fields!


...or 

is a midi cable like an electricity wire where the transfer is instant 
beacue
it entering one elctron on one end simply pushes the last one out on the 
other
end.....
