The flag information is stored in the index, and for Maildir backends the first 26 flags are stored in the filename as well. In other words, access to flags is pretty dang fast, and for Maildir storage, never requires opening the message or parsing headers.
Ok, good! I'm using maildir. (while I like the simplicity of mbox folders, I have some archive folders with up to 30k articles, and maildir sounded a lot better for these)
[snip!]
Large numbers of keywords (esp. more than 26), though, hasn't been tested a whole lot, but should be reasonably fast (largely because of the index and cache files).
While I don't have the exact number, I don't think Gnus nnimap uses more than 26 total.
So that sounds good.
Thanx for the information!
