A close friend of mine is a Vp for a major media company... etc. heavy hitters. Anyway, he wanted to know "are you familier with load scaleablity of drupal - ie > can it handle extreme traffic... like - major traffic during a world wide ticket sale?"
He mentioned (off the record) another superstars site (done with Drupal) "and the performance is terrible - like very very terrible..." That site wasn't one that they put up... but he wanted to know what could be done about it. Was there any testing / performance data on it. He liked what he saw with Drupal but needed more info before he was willing to launch a site with it....
I said, to be honest, I really don't know. "alot of it just could be the flash audio is sucking up to much processor
anywho - in short - i'm looking for samples of drupal that preform under load - ~100k unique visitors a day, prob in the millions of page impressions a month"
Does anyone have any info on this? Any suggestions?
