I have a central offfice running Exchange, SQL and file sharing on a Windows 2k server platform. This office has a 1MB (down stream) satellite internet link. I have a VPN server/firewall (Watchguard) handling VPN duties using PPTP. Connection, authentication and file transfer are fine (although latency affected to the usual degree), but any data handling through Outlook and the SQL agent is really slow. I am fully aware of the latency implications and reason for this, and I think that the slow transfer rate for Outlook is due to the way it or the PC handles packets i.e. it waits for acknowledgement of receipt before sending ther next packet of data. My aim is to find a method of increasing packet size or altering the way the PC's handle packets to speed up the process and get the data through faster. The alternative is to use modems to dial in to, which I want to avoid if possible.
