I moved to chert after id:"87ocl1lut1.fsf@yoom.home.cworth.org" and my notmuch-hello with 15 saved searches appears in a couple of seconds when freshly loaded, faster when switching back to it after use. That may well be slower than just tag searches but it's not yet at a threshold where I notice it.

Very non-scientifically just using time and vm/drop_caches on my netbook, having tagged all mail sent to the list address with 'notmuch', I seem to get much the same performance: $ time notmuch search tag:notmuch > /dev/null real 0m21.074s user 0m4.740s sys 0m1.916s $ time notmuch search to:notmuch > /dev/null real 0m20.280s user 0m4.600s sys 0m2.048s $ time notmuch search to:notmuch@notmuchmail.org > /dev/null real 0m21.790s user 0m5.044s sys 0m2.008s
