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 can be three Spam Scanner engine instances
running simultaneously. The number of Spam Scanner instances can be
controlled by using a command-line switch for F-Secure Content Scanner
Server.
To change the value to 5, so that a maximum five mails can be processed
at the same time, type:
fsavsd.exe --spam-scanner-instances=x
(x is the
value you want to take into use), for example:
C:\Program Files\F-Secure\Content Scanner Server>
fsavsd.exe --spam-scanner-instances=5
