Which communications and how much slower?

In theory not, but in practise please notice that for example with mysql you may switch from unix domain sockets (usually used in "localhost" case) to normal inet socket communications etc. which may affect your overall feeling of "speed".
Knowing details and numbers etc might help here to rule out a jail specific problem.
Bjoern A. Zeeb You have to have visions!
It does not matter how good you are. It matters what good you do!
