Samba and OpenVPN: where are file access delays coming from?

I have it on hearsay that windows explorer does such things if the server is on the same subnet. Is this the case with your vpn?

There are registry settings that I can't remember that help you stop such behaviour.

I've been away for a few weeks but I'm due to post some samba4 patches to help optimize this sort of thing using samba as a caching proxy.

Hi Sam,

I took your advice and with result! Client is apparently downloading the
entire file just to see the properties (in general this is being triggered
with every right click action). Client software is Windows explorer. I tried
4 different file explorer software packages, but with the same result (not
surprisinly as the are based on Windows explorer and probably use the same
API).

Outcome is one of 3 things:

-This is normal Samba behavior (can test this when performing the same
action in the local lan instead of through VPN)

- my config is faulty

- Most explorer software just sucks:-)
