in reply to Profile figures for /usr/bin/podbrowser suddenly running very slowly

There's something garbled in your
1880.71    utf8::SWASHNEW (recurses: max depth 1, inclusive time 83┬╡s)

What does the inclusive time look like? Maybe something's broken in the utf8 handling?

    Ohhhh my most grovelling apologies.
    The numbers in my original posting are hopelessly and horribly wrong
    The correct numbers are in the table below
    And my question becomes:-

    • How to investigate reason why computer "Sheep" spent so much time in podbrowser subroutine main::search_input_changed (Part A. of the table below)

    (Parts B. and C. of the table below, show that there were differences between the two computers in the lists of subroutines in nytrpof/index.html
    Could this be because I failed to give podbrowser the same task in the two computers?)

    Result of running perl -d:NYTProf /usr/bin/podbrowser on 2 computers "Sheep" and "Tiger"
    Data are "Inclusive Time" (ms); from the tables nytrpof/index.html
