7.4. Performance
The Engine performance settings dialog (linked to via the Performance item of the
left navigation) offers the Anti-Spam component performance settings. Move the
slider left or right to change the level of scanning performance ranging between Low
memory / High performance modes.
· Low memory - during the scanning process to identify spam, no rules will be
used. Only training data will be used for identification. This mode is not
recommended for common use, unless the computer hardware is really poor.
· High performance - this mode will consume large amount of memory. During the
scanning process to identify spam, the following features will be used: rules and
spam database cache, basic and advanced rules, spammer IP addresses and
spammer databases.
The Enable on-line checking item is on by default. It results in more precise spam
detection via communication with the Mailshell servers, i.e. the scanned data will be
compared with Mailshell databases online.
Generally it is recommended to keep the default settings and only change them
if you have a valid reason to do so. Any changes to this configuration should
only be done by expert users!
