34 Understanding system requirements
Factors that affect performance
group policies as necessary but be aware that using a large number of policies
may affect performance.
Unresolved messages – Deleting quarantined messages with unresolved
recipients can improve performance significantly.
Note: This feature is only available if you are using LDAP for authentication. For
information on configuring LDAP servers and Spam Quarantine, refer to the
Symantec Mail Security for STMP Administration Guide .
Data pruning – Following are recommendations for improving performance by
minimizing data overhead. Note that these numbers are suggestions only. If you
are legally bound to retain data longer, you should consider archiving it and
storing it offline.
■
Set log levels to Warning and specify a 7-day retention limit.
■
Set report retention to 7 days and only store report data that you need.
■
Set Spam Quarantine message retention to 7 days.
Note: For information on these operations, refer to the Symantec Mail Security
for STMP Administration Guide .
Control Center performance considerations
The Control Center is used to start and stop servers; view logs and reports; set
configuration options; backup, restore, and reset system software; and
consolidate statistics, report data, and logs. Consider the following regarding its
configuration:
■
Number of Scanners – The number of Scanners a Control Center collects
logging and statistics from can impact the Control Center's performance. As
you add Scanners to a Control Center, monitor the Control Center's
performance to ensure that it does not degrade to unacceptable levels.
■
Log level – The higher the log levels, the more data the Control Center must
consolidate over the network. Consider keeping log levels relatively low
unless you are troubleshooting. You can also set logs to be expunged more
frequently.
■
Message Tracking – Through message tracking, Symantec Mail Security for
SMTP components create audit events based on the incremental steps an
email message takes in its passage through the mail flow. By viewing the
Message Tracking Log, administrators can determine easily the fate of a
given message.
