We haven't rebooted to test that yet as the machine is under so little network load I wouldn't expect raising it from 1024 to 2048 RX descriptors to make any real difference, what do you recon? =20 Regards Steve =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
