The code that comes with Mono is very very slow, but you can download the
lastest bytefx code from "http://sourceforge.net/projects/mysqlnet/" and
you will see it is very fast.

I don't know why there is this problem with mono, the mono code of bytefx
is not up to date?

What I don't understand is why you have this problem depending on the
distribution, maybe in SuSE you have the lastest bytefx code installed
