Performance - ESET MAIL SECURITY 4 - V4.2 FOR MICROSOFT EXCHANGE SERVER Installation Manual

4.2.4.4.2

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.
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.
