in certain situations Specifically, don't compute the identifiers-hash before opening the menu but, when it does need to be computed, avoid consider the same arrows over and over. This makes an especially big difference when a region of text is selected that contains lots of arrow heads that all point to a place that has lots of arrows. Specifically, the time to compute the identifers hash for the example in the PR is now about 200x faster (altho this still takes 200 msec, which is why it isn't computed at all in that sequence of steps any more). closes PR 14586 |
