Subject: Simmultanous Connections
We are a company that writes academic software . We are converting our
software to use either PostgreSQL or MySQL. We are leaning toward
PostgreSQL, but, I still have several questions.
I hope someone can answer these for me.
1. I have read the Q&A for postgreSQL and would like to know the
difference between a temporary and a permanant connection. Do you have a connection when you open
the database or only when the frontend sends a job to the backend? If 32 people are running
a module that opens a database is that 32 connections or will it vary as users read and write to
the database?
2. I saw in the Q&A that to run more than 32 simmultanous connects could
be a big drain on our re- sources. Our Linux boxes , in general, are Intel 166 to 500s, 128MG
of RAM and 6.2 to 13 GIG. Can anyone tell me roughly how much resources per connection does
PostgreSQL use?
3. If I have 90 teachers posting grades at the same time, (the grade
posting program opens 5 dif- ferent databases) and 25 secretaries and administrators poking
around in assorted databases looking at information, will postgresql handle that much traffic?
I would appreciate any information you can give me,
Thank you - Jude Weaver.
