MySQL and traffic
 

Can mysql (client) generate ENOURMOUS traffic? I just browsed through not large database, made 20-30 queries, there was NO FLOOD on the screen. Does it act like a telnet or generates some additional traffic (invisible for me)?
Seems, it generated about 100 megs during 10 minutes of work...

I can't see why or how it could do that.
The meaning with the database is to gather information at a central point and only exchange the requested information, not all that is in the database.

The only theoretical situation I could think of is a MySQL server running say locally and storing the database file remotely, but that is not very likely, as you stated it was the MySQL client program.
