Thanks for your reply.
It was not my intention to declare our solution as superior or largely different, simply to propose a simple alternative setup.
I’m also by no means a file system events expert and believe that you’ve spent a lot of time in investigating the alternatives.
I’m aware of https://github.com/EugenMayer/docker-sync/issues/410 and understand that this issue affects anyone relying on osxfs file system events, like our setup does.
At least so far, the CPU/Memory usage of a single lsyncd container seems to be relatively low.
Anyway, that’s not due to our efforts but thanks to the creator of lsyncd.
