Hi I'm wondering how efficient is the exists function? Here's what I'm doing. I got a list of ID's from a db query and push them into a hash. I want to check if a certain ID exists from that db call.

 if (exists $hash{'some id'})

Is this efficient? The number of ID's returned will sure increase on a daily basis (right now it's just over 3000). Just want to know what is the most (or almost) efficient way to do this.
