[phpesp-general] CPU overload

[Wendy D. <wd...@ma...>]

phpesp v.1.6.1
Hello,

I work in a school district where phpesp is installed on our district 
Web server.  A teacher set up a survey that allowed students to vote for 
student council representatives.  There were 8 questions on the survey, 
radio buttons. (choose one only).  The voting could not be completed 
however because, as later investigation showed, the CPU was 
overwhelmed.  I do not know what error message, if any, the students got 
when trying to vote.  My guess is the browser just wouldnt' respond to 
any user inputs.

There were between 40-50 students voting simultaneously.  The survey was 
configured to send results to two email addresses.  And .. the district 
home page, also on the district Web server,  contains a Lasso database.

I suppose any number of these elements could have contributed to the CPU 
overload, but I was wondering if anyone had any other ideas as to why 
this happened?  Is there a maximum number of simultaneous users?  
(should future surveys limit voters to, say, 10 at a time?)  Should only 
one email address be used?  Any thoughts are appreciated.  Thank you.

Wendy
