It may depends on your filter function. XML operations are generally slower
than operations on other types. You should see some speed improvement if you
convert your XMLListCollection to an ArrayCollection of Strings.
As it runs the filter function on each item in your list every time and once
filtered out an item will not show again in the list so adding a filter cache
should improve speed as the user types. Reset the cache on focus in or
backspace.
Something like this, untested and may not run as it, but it should give you an
idea of what to try.
private function filterLocation(item:Object):Boolean {
value:String = item as String;
if (filtered.hasOwnProperty(value)) {
return false;
}
|f (value.indexOf(userText.toLowerCase()) >= 0) {
return true;
}
filtered[value] = true;
return false;
}
Thanks,
