petea/sage — Issue #14: High CPU load with idle Sage after checking feeds
Author: petea

State: open

What steps will reproduce the problem?
1. Run "top" command in a terminal window
2. Start sage from the firefox tools menu
3. Click on check feeds icon in sage sidebar

Note: This is on a Linux (Ubuntu) system. I don't know if it happens
in other operating systems. Run some other cpu monitoring program in step
1 to test it out.

What is the expected output? What do you see instead?
I would expect firefox cpu usage to rise and then drop back to 1-2% after
the update completes. Instead, I see cpu usage for firefox rise and stay
high even after sidebar update ends.

What version of the product are you using? On what operating system?
Sage 1.4.6, Firefox 3.5.9, 32bit Ubuntu 9.10

Please provide any additional information below.
How high cpu usage stays seems to vary. It can be as high as 40-50% or as
low as 15%. Closing and re-opening the sage sidebar will immediately drop
firefox cpu usage back down to 1-3%.
