Hi Ben, I had some experience using client on remote server and it is not easy give a good answer because depend on the number of records, the query and records size.
My experience with a new costumer that moved his server in a remote provider was dramatic! A developer put an image field in a table so if you make a query and the selection of records doesn’t contain image the client work fine with 2mb/sec, but if you have for example the first record of a selection with an image of 1.5 MB you need a connection at list of 10mb/sec. The database structure and query are the most important aspect to consider. Table that use any file or image inside the records should be a problem and query with field that update the selection every new char could be another problem. I work every day with remote 4D database with out image inside the records and with 10mb/sec 4D work fine with 2mb/sec is acceptable less could be very slow to give the selection back and also write code.
