I made some more performance benchmarks with my real life data
I deactivated my "special sort" xSortListe handler and replaced it just
by:
1. sort lines of tListe numeric
2. sort lines of tListe international
(though it is not a solution for my sorting feature, but just to drill
it down)
LC 6.5.2, average times:
My repeat loop: 14 millisecs
plain Sort numeric: 3 millisecs
plain Sort international: 128 millisecs
LC 7.0.5, average times:
My repeat loop: 55 millisecs (+393%)
plain Sort numeric: 8 millisecs (+267%)
plain Sort international: 4100 millisecs (+3203%)
Oh dear. That "sort international" performance is really not very good
at all, is it? I think we will need to address this soon!
I was going to suggest trying the following but perhaps it will not make
much difference because it still uses "sort international"
function TiemoSort pList
local tSorted, tLine, tNumeric, tAlpha
repeat for each line tLine in pList
if isNumber(first char of tLine) then
put tLine & return after tNumeric
else
put tLine & return after tAlpha
end if
end repeat
sort tNumeric numeric
sort tAlpha international
return tAlpha & tNumeric
end TiemoSort
Thank you for sending your stack. I hope it will enable us to deal with
your problem promptly. :-)
