Multiple rails app / single database

Hi,

I was wondering if there would be a problem (in terms of
memory/peformance/etc) running multiple rails app (say about 6) on one
server, all of which share the same database.

Would this mean 6 fcgi (dispatchers) running and 6 opened connections to
the mysql server?

Here is an article that reference “minimizing the amount of fcgi
listeners” which lead to my concern, but not sure if that applies to
what I am doing with multiple rails app.

If it matters, I’m on textdrive (shared business hosting) and using
mysql db.

Thanks!

Truong-An.
