Most testing has been on a Lan or on the local machine for local VFS use cases.

This layer eschews responsibility for multiple concurrent clients for simplicity. No promises you'll get either decent performance or proper cache invalidation when using it that way. It tends to be conservative in not filling in all the opportunistic caches.

There's a hook the backing application can use to tune reads and write sizes that becomes much more relevant in a network case. How those should be set in practice isn't something I've spent time on.
