[Bug 574910] Re: High load averages on Lucid while idling

[James Turk]

John,

I'm so frustrated with this that I'd be happy to try anything, including
however many test kernels you throw at me.

I'm curious though --  If you start up an EC2 instance of your own are
you not seeing this behavior?  After noticing the latest AMI release I
decided I should try spinning up a micro from ami-6006f309

Without even waiting I can start up an instance and see the load go over
1 before I've had a chance to start any services or install anything.

A micro instance started 9 mins ago:

$ date && uptime
Sat Sep 25 03:19:21 UTC 2010
 03:19:21 up 3 min,  1 user,  load average: 0.58, 0.22, 0.08

$ sudo aptitude install postgresql # doesn't have to be postgres, but
basically any service that does anything (tried in past with nginx,
mongodb, hudson, etc.)

$ date && uptime
Sat Sep 25 03:25:14 UTC 2010
 03:25:14 up 9 min,  1 user,  load average: 1.40, 1.04, 0.48
$ sudo aptitude purge postgresql

$ date && uptime
Sat Sep 25 03:29:27 UTC 2010
 03:29:27 up 14 min,  1 user,  load average: 0.35, 0.81, 0.52


the same test with the new amazon linux AMI


$ date && uptime
Sat Sep 25 03:40:38 UTC 2010
 03:40:38 up 5 min,  1 user,  load average: 0.02, 0.18, 0.09

# install & run a postgresql server

$ date && uptime
Sat Sep 25 03:52:30 UTC 2010
 03:52:30 up 17 min,  1 user,  load average: 0.00, 0.03, 0.06
