ID: 24362 Updated by: rasmus@php.net Reported By: grandadmirale at yahoo dot com Status: Bogus Bug Type: Performance problem Operating System: Linux PHP Version: 4.3.2 New Comment: Without buffering this script runs quickly. There is no bug here. Previous Comments: ------------------------------------------------------------------------ [2003-06-28 17:27:14] grandadmirale at yahoo dot com Turning it off does NOT fix this problem. ------------------------------------------------------------------------ [2003-06-28 16:29:40] grandadmirale at yahoo dot com That's the thing though, as a script writer I can't disable that option, I don't see why it's not setable by script, all other session options are. Sure I can distribute a message saying to ask your host to disable this if it's on, but that's not very effective. ------------------------------------------------------------------------ [2003-06-28 16:26:57] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Yes it would. Not only does it force increased memory allocation but is also causes parser to go through the data. This can be quite slow, while on a small output couple of kb it may be too small to notice on large files you'll definately feel the impact. If you don't like the performance loss disable that option. This is not a bug. ------------------------------------------------------------------------ [2003-06-28 16:23:23] grandadmirale at yahoo dot com Yes it's on... but would it really slow it down THAT MUCH? I will try turning it off on one of the servers tested on, but this becomes a problem since it's not an option for people to turn it off since it's not changeable via script... which might be a good thing to change, I don't really see it presenting a problem, any good php script adds the sessid itself to the url anyways. ------------------------------------------------------------------------ [2003-06-28 15:25:02] iliaa@php.net Are you using session.use_trans_sid if so that would explain the performance drop. Since php would need to buffer the entire output of the script and pass it through a parser that would add a session id to every URL. This would explain why outputing longer text would get progressively slower. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
