They more or less don't.  They only come in to play for applications that explicitly ask for them and the implementation is fast and efficient (it's tied in to the standard Lustre locking mechanisms)

Hi Torsten,
Thanks that worked!

Do you or anyone on the list know if/how flock affects Lustre performance?

Thanks again,

I know nothing about Elastic Search, but have you tried to mount Lustre
with "flock" in the mount options?
