269608 - mozilla mail/news scales badly with very long threads in newsgroups

Status: RESOLVED EXPIRED

(MailNews Core :: Networking: NNTP, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0

mozilla mail/news is blocked for a long time, if there's an extremely long
thread in a newsgroup

Reproducible: Always
Steps to Reproduce:
1. subscribe to the newsgroup de.sci.mathematik
2. wait half  a minute (with Athlon XP 2800 512MB RAM)
3. read the thread "Hat Cantor doch geirrt" as an example for an extremely long
thread.

Actual Results:  
mozilla mail/news ist blocked for a long time.

Expected Results:  
1.) at least the browser and other components should continue to work
2.) the sort algorithm should be faster  - consumed time seems to grow
exponentially with the length of the thread. The total number of messages in the
newsgroup is not a problem. I've downloaded 16000 headers from this newsgroup
and 15000 from another newsgroup ( de.comp.os.unix.linux.misc) which is ok in
performance. The problem with de.sci.mathematik seems to be the length of the
long thread. 
I don't know which algorithm is currently beign used, but maybe there's a bette one.
