Everything get slower with 8.3

[Olivier Nicole]

Hi,

Few weeks ago I upgraded many systems from 7.4 to 8.3 and since I feel
that everyting has got much slower:

- connecting a new shell takes 5 secnds between the password and the
  first promt;

- imap got slower to the point imp/horde times out

- amanda back-up will not complete

- etc.

I don;t know what to look for to correct this.

TIA,

Olivier
