Improving performance Non-citrix configuration.

Hello,

I was wondering what would be the best way on improving performance when using the DOORS client via a VPN connection without a citrix configuration; I was recently in Asia where employees need to access our database in the USA and the latency is 200+ ms on average 260ms?

There is not an awful lot you can do about this. DOORS has always had a reputation of not being very tolerant to network connections that have a long ping time. The generally accepted convention is that ping times at around 50ms is when performance starts to noticeably drop off and then get progressively worse to the point where it fails. The most effective solution, but costly, is to deliver DOORS to remote PC's via a thin client platform such as CITRIX or Microsoft's Terminal Services.

CITRIX is the more polished and feature rich of the two, but they both work on the same principle of users performing a remote desktop connection to a distant server that is on the corporate LAN, and running a DOORS client installed on that remote server. All that is passed between the users PC and the server is low bandwidth data such as screen information and interactions with the keyboard and mouse.

If I recall correctly, the Windows Server operating system comes with Terminal Services installed and at least 2 licenses (it could be more). If VPN access is only occasional, then maybe this is an option.

I believe 25ms ping is the threshold between tolerable and untolerable; at least for large modules.
