Description Stefan Plewako 2006-11-02 14:23:13 UTC 
Description of problem:
Lifrea start to horribly slow render feeds views and takes in this time almost
100% cpu.. it's annoying because sometimes it takes up to few minutes for each
feed/subscribtion.

Version-Release number of selected component (if applicable):
liferea-1.0.25-1.fc6

How reproducible:
Always

Steps to Reproduce:
1. Run Liferea
2. Click on any feed to read it.
  
Actual results:
It takes from 20 up to ~180 seconds with about 90% usage of cpu to display feed
content.

Expected results:
Normal performance will be restored (like from fc5's lifrea realeases would be
enough)

Additional info:
When running liferea with debug option, I see in a log something like this,
after I click some feed to read it:
$liferea --debug-verbose
[... startup initial logs ..]
(     feed.c:602:       feed_add_item)(thread 0x819e388)(time 14:59:19) : check
new item for merging: "Odometer stopped working"
(     feed.c:701:       feed_add_item)(thread 0x819e388)(time 14:59:19) : ->
item added to feed itemlist
[... many many lines like above, for evry feed entry, in every subscription ..]

don't know if this is correct, how it affect performance, but checking every
feeds entry every time I click any feed is very strange for me.
Comment 1 Stefan Plewako 2006-11-05 18:46:39 UTC 
Ok, I clean up ~/.lifrea/mozilla/* from an old Mozilla Suite profile (or
precisely: Seamonkey via symbolic links) (btw it would be nice, if this coluld
be posibble by default with some backup of an old profile), and customize new
Firefox profile, there is a progress - but still it is much slower than in FC5 -
this is normal?

Are you still experiencing this?  If you are, could you attach your opml, so I
can try to reproduce the behavior, since I can't currently.

Closing since unable to reproduce, and bug reported has failed to respond to
information request.
