Operation in Low Connection Speed Mode
The main purpose of indicating a low speed of client connection at system startup is to adapt the system operation to use of slow connection channels. The system cuts costs by lowering the number of server queries and abandoning transfer of insignificant information.
Connection speed is selected in the dialogs of infobase editing and adding, upon thin client launch (1cv8c.exe), on pages to setup parameters of connection to infobases. The available options of connection speed are: Regular, Low, and Select at startup.
If Select at startup option is selected for an infobase, the speed of client connection will be determined by the value of the Low connection speed checkbox in the infobase list dialog. If Regular or Low option is selected for an infobase, the checkbox in the infobase list dialog will not be available for selection and will have the value of a selected option for the infobase.
In thin client mode, the O command line parameter is used to control client connection speed.
In web client mode, the O command line parameter is used to control client connection speed.
Selection of low connection speed mode is visible in the interface by absence of icons of the sections panel subsystems.
Desktop commands and an empty work area are displayed at startup. The work area contains Display Desktop hyperlink. If you need to work with desktop forms, you should open the desktop using this link. If you need to work with other forms and sections, you should open the forms using commands of the panels.
In the low connection speed mode less queries are executed when a form is opened. This is due to the fact that certain time is needed for every server query so the system rearranges the queries to optimize performance by reducing the number of queries which is achieved by sending them in batches.
When working with data in the low connection speed mode you should bear in mind that a server notification of closing a form that locks some data is sent 20 seconds later or simultaneously with a query to open another form.

In this mode when you select data for a text box from a list or when you use string input, instead of reading data from the database each time the previously received data will be used where possible not to send unnecessary queries to server. If new data appear in a database and you need to select them while they are not displayed in the list yet, you should repeat selection for the text box (by pressing the selection button again without moving to another box) or update the list (using the Update command or pressing F5 in the selection list form). Also during input by string the selection list will not be opened automatically on timeout in the entry field. Instead you should use the Arrow Down key to open the selection list.
