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

+\r
+Very non-scientifically just using time and vm/drop_caches on my\r
+netbook, having tagged all mail sent to the list address with 'notmuch',\r
+I seem to get much the same performance:\r
