lsof

I knows I can use the command

lsof -p xxxx | wc -l

to know the count of opened files op a process, it works, but however, it is just too inefficient. I have some server process which have too many socket files, the wc -l method never return the result. So, what is the efficient way to know how many files opened on a process?

Thanks.
