Review the needs of your site before you decide how often to issue sp_text_notify.
Using the sp_text_notify system procedure produces a load on the Full-Text Search engine as the system procedure reads the data and updates the text collections. Depending on the size of this load, the performance hit for issuing sp_text_notify can be substantial. Because of the performance implications, you must determine how up to date the indexes need to be. If they need to be current (close to real-time), then you will have to issue sp_text_notify frequently (as often as every 5 seconds). However, if your indexes do not need to be that current, it may be prudent to wait until the system is not active before you issue sp_text_notify.
You cannot issue sp_text_notify from
within a transaction.
