  16. Conclusions from Last Time • High-frequency SELECTs are killing us

  17. Hypothesis • When clients check for new email they send a SELECT • (They should send a NOOP) • Users are setting their clients to check for email every minute

  18. 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.)

  19. Our Plea • See if your users are polling < 5 min • 10 min is better • You can always manually check for new email • Help them change their polling time if needed

  20. New Data • We are logging SELECTs • More analysis

  21. Something Funny • A funny thing happened on the way to the user-migration fest... • A familiar name showed up

  22. And a surprise • He only uses webmail

  23. New Data • Webmail does a SELECT every five minutes • But does an EXAMINE as soon as possible after the SELECT • How can we see this?

  24. Clustering of SELECTs Δt t SELECT (user, mailbox) SELECT (user, mailbox)

  25. Clustering of SELECTs Δt . . . 29s 30s 31s . . .

  26. Clustering of SELECTS

  27. Clustering of SELECTs

  28. Clustering of SELECTS

  29. Conclusions • 60-second polling is a problem • The webmail upgrade put us over the edge

  30. Solutions • Checking in on the heavy users • (9-days of data, 55-s to 75-s) • Analyze the Webmail code • Architecture changes • More hardware
