Antivirus configuration parameters
Antivirus is one of the processes that can use a lot of hardware resources ( memory and CPU's ). An aggressive antivirus policy can decrease the performance of the application and affect end users feeling with user interface.
Antivirus analyzer can work in two mode ( depending the value of background.antivirus.check parameter ):
- Live mode.
- Batch mode.
Antivirus checker in live mode can dramatically decrease the user interface end user feeling. Take in consideration that to analyse some documents the antivirus can take up to 3 seconds or more what will be added to the uploading time process.
