you have to give a lot more information.

7 * 30 = 210 concurrent connections. Depending on the
load (what these connections are doing) and on DB server specs,
this might be pretty good performance. Or not. it all depends:

DB Server specs?
All connections are busy?
what kind of queries?
what happens when the DB server "cant keep up"?
etc, etc, etc.
