ProjectWise explorer slow performance for VPN home workers

Hi, Our compnay promotes homeworking. We are starting with ProjectWise and working from home is great with Delta file transfer but working in ProjectWise Explorer to change states in our rule based workflow is minimum 5 times slower (e.g. 25 secs instead of 5 secs at the office, 120 secs instead of 25 secs) through our VPN connection Wifi or cable (not much difference). The home Internet is the fastest on the market. Any advise ? citrix ? Thank you very much in advance.
