note 52652 added to function.ob-start

I don't claim to understand this--I would have expected the exact opposite--but it seems that ob_start() ... ob_end_flush() can massively improve perfomance, by at least a factor of 10 (admittedly a small number of samples). I tried this after discovering that I could move a large (100ms) bottleneck in one of my scripts into echo "<!-- about 40 characters of junk -->"; which clearly shouldn't have taken long to run. My unfounded theory is that without buffering, the interaction between PHP4.3.4 and Apache is not optimized, whereas with buffering, PHP delivers the entire page at once, which Apache handles better. I should add that this is under https. ---- Manual Page -- http://www.php.net/manual/en/function.ob-start.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52652 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52652&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52652&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52652&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52652&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52652&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52652&report=yes Search -- http://master.php.net/manage/user-notes.php
