I guess until we know what that network share is and how it works, we cannot really progress. Taking 10 ms to fetch the 19 KB file is definitely not great, it would be ~50 LAN roundtrips.

Probably that network share does small reads if small reads are requested.

Might be good if the author ran `dd` or a similar tool where the read buffer size can be controlled.
