To me comparision sound right becasue In the same machine with wine you access data and use a gui In my application IO access is the most important element In all my harbour application (ADS and dbxcdx) When Upgrade Speed of disk and lan my application work fast

Multi Tier application is good for scalability of application with more that 200 user you must -will use a multi Tier application so you can expand speed Database server Or applIication server changing cpu,memory,disk when user grow How many user use your xbase++ aplications under wine+samba +freenx server ? wine+samba +freenx are 1 tier becase run on same machine IMO will be better harbour+Xhb+hbqt+freenx server -- Massimo Belgrano _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
