Connection/Thread priorities

[Christian Reusch]

Hi,

I have a general question concerning multiple connections:

Connection 1: Program that makes updates to a table
every second (Server program)

Connection 2: Program that sends a large query to
MySQL-Server (Client program)

Problem: If query from a client (large query) is sent,
Updates on Connection 1 take a very long time, so that
server does not work properly anymore.

I thought, if a database server is multi-threaded, this
should not happen.

Regards, Chris
