more efficient

[Yamamoto]

which way is more efficient for a trigger

triggerClientEvent(root, "....", root)

or 

for k, player in ipairs(getElementsByType("player")) do 
  triggerClientEvent(player, "....", player)
end 

 

[Tekken]

The first one, for sure.

Also you may see on the wiki page of triggerClientEvent

Note: It is marginally more efficient to pass one large event than two smallers ones.

 

Btw triggerClientEvent ("name", elm) you don't need to specify the first root as it's already by default. Hope this helped you.
