A Pointed Critique of Thunderbird 3's Performance Compared to v.2

Posted by timothy on from the should've-stopped-while-ahead dept.

PerfProtector writes "Did you recently install Thunderbird 3 or upgrade from Thunderbird 2 to Thunderbird 3? Did you notice any severe slowdown in your machine or a major decrease in its performance? Well, many people around the world encountered these problems. We wrote a technical analysis about the severe problems that are caused by Mozilla Thunderbird e-mail client. These problems include anomalous usage of CPU, memory, hard disk and Internet bandwidth. You can read the full analysis, including several graphs that show how bad the situation is and what went wrong from Thunderbird 2 to Thunderbird 3. For example, while CPU utilization of Thunderbird 2 is usually between 0% to 10%, with an average of 0.3%, Thunderbird 3 CPU utilization is between 5% to 80%, with an average of 30% — 100 times more than Thunderbird 2. In addition, during long periods of time, Thunderbird 3 used more than 50% of the overall CPU resources.This behavior slows dramatically the whole machine." It's worth noting that this analysis comes from developers who have developed a (freeware) tool they claim will improve Thunderbird's performance, but they explain also how to do so with manual changes.

    For example, while CPU utilization of Thunderbird 2 is usually between 0% to 10%, with an average of 0.3%, Thunderbird 3 CPU utilization is between 5% to 80% with an average of 30% -- 100 times more than Thunderbird 2.

    Actually, 30% is only 99 times more than 0.3%. If you wanted to use the 100 figure, you'd need to say "100 times that of Thunderbird 2".

    This is why all software you use must be open source, this wouldn't happen if people were able to get in and see the code that is actually causing the problems

    Oh My God, Quick before anyone looks I've found the source for Mozilla Thunderbird 3.1 stop the freakin presses!!!!

    ftp://ftp.mozilla.org/pub/thunderbird/releases/3.1/source

    Now we can fix all those problems in the pesky proprietary Thunderbird.
