I could be wrong but I am seeing strange, much longer page load times on mobile Safari from an iphone when connecting to litespeed 4.0.x There are some subtle differences in Safari on iphone. Perhaps there is a timeout issue. Does anyone have an easy way to test the same content from apache vs litespeed off their iphone? I don't want to start "pointing fingers" until I have more data. I know Chrome on Android is not experiencing any problems and it's also webkit based but there are definitely core differences between the two browsers.
