Mapped drive performance is poor over Cisco Anyconnect VPN

Hi All,

Has anyone got any tips to improve mapped drive performance for remote VPN users ? Everything on the VPN performs fine apart from when access mapped drives. Files take a while to open and browsing files structures can be a bit sluggish. Even right clicking files for options such as copy or open stalls and causes file explorer to go into ''not responding''

I have looked around online but can't find anything except people reporting that mapped drives are poor over VPN as SMB traffic is very chatty.

I am tunnelling all traffic for remote users so their traffic is treated the same way as if they are in the office and their internet based traffic is filtered by sourcefire. We have plenty capacity at our internet gateway so that isn't causing the problem.

Any ideas ?
