Thanks. Actually all the people will take it. It is an internal survey and they are being told by their managers that they must take it.
That said, I would expect about 12-25 people hiting the site at any one time (If I send out all 400 invitations at one time). Also, it isn't a one shot survey submission. It is a 3-4 question at a time kind of survey and about 200-300 questions total. So there will be lots of reads/writes. Some of the initial queries are complex (lots of joins, etc.) so I am a little worried about SQL performance. Anyway, I'll take this to the the list mentioned by J.Petersen: [EMAIL PROTECTED], but if anyone has anymore useful comments I would welcome them. --- Peter Lin <[EMAIL PROTECTED]> wrote: > > from a pracitcal perspective, chances are at any > given time there will only be 1 person submitting > the completed form. 400 seems like a very low number > to me. > > Now if you're talking about a survey that is sent > out to 10K people with a window of 5 hours to submit > it, it probably won't be a problem.
