Subject: [phpesp-general] Very high traffic surveys

Hi All,
	I may be developing a survey that would be answered by
approximately 200,000 users over a period of several days (All the =3D3D
students of
a major university system).  I would like to limit it to one dedicated =
=3D3D
server, as I=3D3D20
have an available server, but would not want to install any extra hardware =
=3D
=3D3D
or deal with the headaches of
rewriting phpESP for clustering..
	Thoughts so far:
	*Cache the survey page as an html file, with the submit pointing
to phpESP, thus halfing the mysql load.
	*Optimize the indexes in the mysql database.

	Anyway, does any of you have any experience with large volume
surveys, and if so what sort of pitfalls have you run into?


Regards,
Erek

What kind of hardware will it be run on? =3D3D20
Saving the survey page and adding a few indexes as you mentioned sound
like good ideas.  However, if you're using save/restore or multi-page
surveys, caching this way might be a problem.

You should also look into optimizing your Apache and mySQL daemon
configurations as well.  Normally out of the box, Apache and mySQL
aren't configured to handle something like this nicely.
