There are some things you can do to affect the frequency of the updates:
  • A client table could ask the server to limit the update frequency. e.g. in the web client you can use the setRequestedMaxFrequency of the Table object.
  • It's possible to set a maximum update frequency on a user/item basis with the getAllowedMaxItemFrequency of the MetadataProvider.
  • The <max_delay_millis> element on the server configuration can be used to pose an upper bound to the maximum update frequency for items not subscribed with unlimited or unfiltered frequency (see also http://www.lightstreamer.com/vb/showthread.php?t=123 ).
Hope that helps.
