Hi all, I'm having a great time patching up the vim frontend, but I've got an issue that is in the backend, and seems far above my head at this point:
notmuch search tag:foo is slow! (when my e-mail files are not already in the disk cache) I saw on my activity monitor applet that it was using mostly i/o, and started to wonder if it was opening every e-mail. I little work with strace and searching revealed that this command was opening many many e-mail files from my maildir(s). I spent a little while digging around in the notmuch source, and didn't see where it was opening the email files. I don't think the search command should be opening the files. So my questions: 1) Why is it opening the e-mail files? What information is being read? 2) Do you agree that it should instead get this information from the database? 3) How hard would it be make this fast? What would it take? 4) Who wants to do it? I'd like it to be able to spit out 1000 threads in under a second. Preferably under 100ms. Thank you, -- Jason P.S. I mean really slow... notmuch search tag:foo took 0.5 seconds for 32 threads notmuch search foo took 6.4 seconds for 130 threads Everything's getting into my cache, so I can't easily get lots of numbers. For a while I had a simple search (tag:foo and tag:bar) which returned about 600 threads, and it would frequently take seconds.
