Optimizing F-Secure Spam Control Performance
Due to the nature of DNSBL/RBL, processing time for each mail
increases when DNS queries are made. If needed, the performance can
be improved by increasing the number of mails being processed
concurrently by F-Secure Spam Control.
By default, the product processes a maximum of three e-mails at the
same time, because there are three Spam Scanner engine instances
running simultaneously. The number of Spam Scanner instances can be
controlled by modifying the
F-Secure Content Scanner Server / Settings /
Spam Filtering/Number of Spam Scanner Instances
setting.
To take the new setting into use, restart F-Secure Content Scanner
Server. For instructions, see “
Starting and Stopping F-Secure Internet
.
IMPORTANT: Each additional instance of the Spam Scanner takes
approximately 25Mb of memory (process fsavsd.exe). Typically
you should not need more than 5 instances
