my nexus 5 got 16886 score in antutu benchmark application.
is this good score or bad?
I wouldn't worry about the benchmark score as long as the performance of the phone is still good. Benchmarks are pointless, some phones (GS4 for example) have high scores on benchmarks, but still lag considerably more than similar or lower-scoring phones.
The Nexus 5 is one of, if not the smoothest Android phone out, ignore the benchmark scores of other phones

woah. can u tell me if how many space u have used already in the phone.
i have 32gb model, and 8gb is left. is this the reason for low score?
I have about that much left too, because I temporarily transferred the data from a few older SD cards onto the phone. I have noticed the battery performing less well than it did before I put all the data on, but I haven't noticed any slowing or lag or other signs of poor performance.
what i noticed is that leave the phone alone with all apps closed for 5-10 minutes, then open only the benchmark application. that's how i got my score now.
