Performance Tuning
Number of DB Proxies
This parameter specifies the maximum number of database proxies that can be used by the mail
scanning processes. This value is relative to the Maximum Number of Processes setting, and should
be increased in conjunction with increases in the number of maximum processes.
Valid settings are from 2 (Default) - 12 (maximum processes), however, setting this value above 8
will result in diminishing performance returns.
TABLE 5. Number of DB Proxies
System Recommended Value Description
M1000 4 (default) This is the default setting and should
not be modified.
M2000 4 If increasing Maximum Number of
Processes above 50, then set this
value to 6.
M3000/4000 8 If increasing Maximum Number of
Processes to 150, then set this value
to 10.
SMTP Connect Timeout
This SMTP parameter specifies the amount of time, in seconds, for an SMTP client to complete a
TCP connection before we drop the connection. This value defines how long ePrism will wait for a
response before timing out. The default is 0, but there is an overall system timeout of 5 minutes for
SMTP connections. Increasing this value may help with sites which have a slow Internet
connection.
SMTP HELO Timeout
This SMTP parameter specifies the amount of time, in seconds, for receiving the SMTP greeting
banner before we drop the connection. The default is 300 seconds, which means that ePrism will
wait 5 minutes to receive the initial SMTP HELO message before timing out. Using a lower
timeout value may increase performance by freeing up more connections. Increasing this value may
help with sites which have a slow Internet connection.
SMTPD Timeout
This SMTP parameter specifies the amount of time, in seconds, to send an SMTP server response
and to receive an SMTP client request before dropping the connection. The default is 300 seconds.
When ePrism connects to another mail server to deliver mail, it will drop the connection if it takes
more than 5 minutes to receive a response. A lower value may increase performance by freeing up
connections. Increasing this value may help with sites which have a slow Internet connection.
