Information Technology at Emory Information Technology Division Technical Services Conclusions from Last Time High-frequency SELECTs are killing us

Information Technology at Emory Information Technology Division Technical Services Hypothesis When clients check for new they send a SELECT (They should send a NOOP) Users are setting their clients to check for every minute

Information Technology at Emory Information Technology Division Technical Services Final Notes Webmail checks every five minutes (and does use SELECT) Some clients have a drop-down menu to select this time (1-min, 5- min, etc.)

Information Technology at Emory Information Technology Division Technical Services Our Plea See if your users are polling < 5 min 10 min is better You can always manually check for new Help them change their polling time if needed
