  50 Dear All,\r
  51 \r
  52 I'm wondering whether there could be some optimisation done. I'm using\r
  53 notmuch remotely. I.e. open ssh communication and keep it running using\r
  54 dtach as shown on notmuch website. Works reasonably. I.e. latency of\r
  55 ~1second between key-presses when switching between notmuch buffers.\r
  56 \r
  57 Real pain however happens when notmuch-hello shows all the tags. Then\r
  58 the remote-notmuch slows down by degree of order. I did a bit of\r
  59 profiling, and it seems that all that slowdown is in\r
  60 'notmuch-hello-insert-searches' and friend functions - as seen below the\r
  61 result of Emacs profiler.\r
  62 \r
  63 Could those be somehow improved, e.g. using local caching of the data\r
  64 and refreshing them only when e.g. notmuch-hello-poll-and-update is\r
  65 called? This would considerably speed up the user 'comfort'. It is of course\r
  66 understood that when a new tag is created, it would not appear in the\r
  67 list immediately, but after poll-and-update....\r
  68 \r
  69 \r
  70 any opinions?\r
  71 \r
  72 cheers\r
  73 d.\r
