4.2.4.2.2
Performance
In this section you can set the number of independent scan threads used at a single time. More threads on
multiprocessor machines can increase the scan rate. For the best program performance we advise using an equal
number of ThreatSense scan engines and scan threads.
The Response time limit (sec.) allows you to set the maximum amount of time a thread waits for a message scan to
complete. If the scan is not finished within this time limit, Microsoft Exchange Server will deny the client access to the
email. Scanning will not be interrupted and, after it is finished, every other attempt to access the file will be successful.
TIP: To determine the Number of scan threads the Microsoft Exchange Server provider recommends, use the
following formula: [number of physical processors] x 2 + 1.
NOTE: Performance is not improved significantly if there are more ThreatSense scanning engines than scanning
threads.
