Maximum megabits
The average maximum megabits per second (Mbps) ListManager should use. By default, this setting is "0", meaning use as much bandwidth as necessary.
In some circumstances, ListManager may use all of your bandwidth, limiting other web applications. If
you have bandwidth limitations and would like to prevent ListManager from using all of your bandwidth,
enter the amount of bandwidth (in Mbps) it should be allowed to use on average.
Note that this feature regulates the average bandwidth used by the server. If you are sending out
very large messages, ListManager will send each one as quickly as possible, but then will be idle for
a period so that its average bandwidth is what is set here. If you must eliminate large bandwidth spikes
as well as regulate your average bandwidth usage, you should consider a hardware solution (a managed switch
with rate-limiting).
Maximum messages per hour
The number of messages your license permits you to send per hour. By default, ListManager will be set to use the maximum number of messages per hour permitted by your license. This setting allows you to lower the maximum number of messages per hour ListManager will send.
Contact your account representative at 800-768-2929 or at sales@lyris.comfor more information about increasing the maximum number of messages per hour.
Maximum simultaneous sends
Controls the number of simultaneous email messages ("sends") that can be sent at once. By default, ListManager will be set to use the maximum simultaneous sends for your license.
In general, the maximum allowed by your license will be sufficient. However, if you are finding that your bandwidth or firewall is being overtaxed by ListManager, you may want to set Maximum simultaneous sends lower.
If you are running a site that has a very large number of one-off messages, such as autoresponders, or many subscriptions, you may want to increase the number. Contact your account representative at 800-768-2929 or at sales@lyris.comfor more information about increasing your maximum simultaneous sends.
Maximum CPU bound threads
Configures the number of threads ListManager is capable of using for DomainKeyssigning in the background.
