Tips For Improving Software Performance

 

 

Antivirus software configuration

Antivirus software can drastically impact the performance of VFP applications. While no one disputes the need for antivirus software, if the software scans VFP data files, your performance may suffer. While we are not experts on all possible configuration settings of antivirus software, we can provide some general suggestions:

Disable autoscan on the 'BitPOS' and 'BitExport' directories.
Prevent the antivirus software from scanning VFP data files.
Ensure you have the most recent build of your antivirus software.

 

Enable Network Shares (fixes UAC elevated access issues).

Windows 7/8/10 has a issue where network shares are not always visible when running programs that need elevated privileges, like the BitPOS Installer.

Click this file link Enable_Linked_Shares and save the file to your computer.
To run, right click and select 'Run as administrator' for proper security access to your system.

 

Disable Interrupt Moderation in the advanced settings of your network card.

You can get to this setting by right clicking your network connection, going to Properties or Status, then Properties and clicking "Configure" next to the network card in the "advanced" tab you may have an option for Interrupt Moderation, equally you may not, but if you do, disable it.

 

Disable SMB2 Cache ( Valid only for Windows Vista, 7 and 2008 Server )

With the advent of Windows Vista and Windows 7, Microsoft introduced a new network protocol (SMB2) to optimize file sharing for WAN and low bandwidth and high latency scenarios. To optimize these types of file access scenarios, Microsoft performed design decisions which lead to the inability of the new SMB2 protocol to handle cache coherency of file meta information such as the file size, the last update time and whether the file actually exists on the server ("file not found" status).

As a result of this design decision made by Microsoft, the SMB2 protocol with its default configuration breaks any application relying on shared, concurrent data access. It is therefore absolutely required to reconfigure the SMB2 cache of the local workstation to not cache file meta information.   Click this file link Disable_smb2_cache.exe and save the file to your computer.
To run, right click and select 'Run as administrator' for proper security access to your system.
