Large number of phones

If you have a large number of phones, more than a few hundred, you might need to switch to partial phone updates instead of having every phone update be a full update. A partial update only looks for changes to the IP addresses of known phones. A full update looks for all changes in all known phones. If you have a large number of phones, it can take a while to process a full update.

There are two settings in 

c:\Program Files (x86)\Syn-Apps\BlastNotifier\BlastNotifier.exe.config

 that control the frequency of phone updates and how often the update must be a full update instead of a partial update.

Default values:

PhoneUpdateInterval sets the frequency for updates. FullUpdateRatio sets the ratio of full to partial updates.

For example, if you want to keep the default PhoneUpdateInterval value of 120000 milliseconds (2 minutes) but only do a full update every 20 minutes, change the FullUpdateRatio value to 10. So, every 10th update is a full update, and all other updates are partial updates.

To configure a partial phone update every 10 minutes with a full update every 12 hours, set the PhoneUpdateInterval=600000 and the FullUpdateRatio =7 2 . 60000 milliseconds equals one minute, and 600000 equals 10 minutes. There are 720 minutes in 12 hours that can be divided into 72 10-minute periods.
