"Why it's slower than the competition". The "it's slow because it's XUL" is not correct and it doesn't help promoting Mozilla-as-platform. Unless you have a really old computer, Thunderbird will not be slow because of XUL. After all, Firefox is written in XUL and one of its selling points is that it is faster. --asqueella 09:18, 26 December 2005 (UTC)

Reference to "xul.mfl" file

There is a reference here to a "xul.mfl" file that can get corrupted. I do not see this file anywhere on my current Thunderbird setups (as of January 2013). Do recent versions of Thunderbird not use this, and if not, could the reference to it here be deleted?


Given modern hardware I don't believe this section is currently true/relevant "Why it's slower than the competition". wsmwk 12:23, 5 June 2016 (UTC)

"Thunderbird appears to parse the contents of the entire Inbox folder when it fetches..." is difficult to parse (I didn't attempt to) and frankly I'm not sure it is true today. It should be reevaluated and probably removed. wsmwk 12:23, 5 June 2016 (UTC)

"Thunderbird 3.* uses approximately 50MB within a couple minutes under Windows. ..." is ancient history,and the figures are no longer accurate for current versions and therefore misleading. wsmwk 12:23, 5 June 2016 (UTC)

Thanks for all the edits. I do think however that "Consider lowering that to 1MB" in regard to compact is very poor advice, given today's average hardware capabilities and the fact that there is no way compacting at 1MB vs 10MB is going to get any user on any hardware a performance improvement. wsmwk 10:52, 7 June 2016 (UTC)

Regarding disk defrag - I'm not going to edit further, but just know that 15% is the minumum amount required for XP to do a minimually decent job. But it doesn't necessarily allow for a full defrag and 20-30% may be needed to do a thorough job (nothing to do with speed) - based on my recollection from a few years go. It may be different for OS newer than Vista - unfortunately I haven't kept up with their compact strategies. wsmwk 10:52, 7 June 2016 (UTC)
