Trying above code did reduce the CPU usage by 3 to 4% but now replace child
becomes a problem by taking up 35% of cpu time. I get an array of
textElements and have to iterate over the array in a loop to call
(unlink->update->replace) for each text element. So taking the replaceChild
function out of the loop seems impossible.
Is it possible to take this replaceChild method call out of the loop, when i
just receive an array of text elements?
Thanks,
Naveed
