Hm, always a good idea to run tests before giving an
opinion!

 -- adding by index
local tbl = {}
local k = 1
for i = 1,1000000 do
    tbl[k] = i
    k = k + 1
end

-- using append
local append = table.insert
local tbl = {}
for i = 1,1000000 do
   append(tbl,i)
end

Well, the first snippet is about four times as fast!
