Table.insert first position performance

Typically table.insert is a lot slower than using t[#t+1] = " " but if you want to insert into a table as the first position in a loop, is there another method to do this rather than Table.insert that would perform a lot better, or is table.insert the fastest option if trying to insert to position 1.
