Bug#574033: icedove: downloading many (newsgroup) headers uses too much CPU

[Bernhard Kuemel]

Package: icedove
Version: 2.0.0.22-0lenny1
Severity: normal


When I select a newsgroup with many new postings icedove uses too much 
CPU when downloading the headers. There must be some inefficient
algorithm or polling. This was still annoying on a 2 GHz intel Core  2
duo.
