Every IP has his own 1Gb/s network card. On the end, two clients had a connection to IP 1 and the second two to IP 2. First we used the two onboard NICs and then, one onboard and one external NIC, but without success. We never get more then 112MB/s All are connected through a Cisco Catalyst WS-X4515. The mainboard is a Intel S3420GP. any suggestion? cu denny --=-sr5+TvcYgs/6SAXJIJTy Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEABECAAYFAk2i0UcACgkQKlzhkqt9P+C7sQCghsz2bzM5kGoTFvYTpHN062ef k5AAniD3DooO4NBdJSBuAOyt8RafS646 =TqFu -----END PGP SIGNATURE----- --=-sr5+TvcYgs/6SAXJIJTy--
