System Performance 

The MLS and RETS Systems are shared resources.  The primary function of the NTREIS MLS System is to provide current information to real estate agents in a timely manner. The function of RETS is to provide MLS data to MLS users and third parties.

NTREIS is very concerned about how RETS downloads can impact the system performance of both MLS and RETS, thus resulting in a poor experience for both real estate agents and RETS users. 

NTREIS would prefer not to impose limits on RETS users, either on the amount of data or when data can be accessed.  However, if it is determined that RETS users are consistently running large downloads or has improper/inefficient RETS queries, NTREIS will reserve the right to impose limits on when the queries are allow to run, or how much data can be downloaded within a certain time. 

To ensure the experience is optimal for all users, NTREIS requests all RETS users refrain from running large downloads between 8 a.m. and 6 p.m. on Monday through Friday.  During these hours, please run incremental-type searches.  Large or full downloads can be run after 6 p.m. and before 8 a.m. 

NTREIS also requests that users do not run incremental searches on any one RETS Class more frequently than 15 minutes apart. 

If you have any questions, please contact rets@ntreis.net.
