When my (JDBC based) SQL client and the database server are on the same computer, I can store a 45MB file about 4
seconds,a 240MB file in about 20seconds
When I do the same with a server on the (same) network, the 45MB take about 9 seconds, the 240MB take about 60 seconds.
So yes, these numbers sound a bit surprising.

How far are your app server and the database server apart?
Maybe it's just a case of a slow network
