--nextPart2669217.BftJGTctvS Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Goodevening lists, I am toying with Freebsd 7 to see if it will and how it runs on my new Asus= =20 M2N mainboard. One of the things I noticed is that when running=20 7.0-Current-200704 the throughput of the SCSI drive seems halved. When=20 running 6.2 throughput is doubled/normal. Throughput is measured with the following command. dd if=3D/dev/zero of=3D/usr/test where /usr resides on da0s1f On 7.0 I get about 33MB/sec On 6.2 I get about 69Mb/sec I did not make any changes, installation is fresh from CD with Minimal as=20 distribution. As the NIC is not yet supported by Freebsd and I haven't got it working yet= =20 (need to get a supported nic in, hopefully tomorrow or the day after) I can= =20 only provide the below information. I had to type it reading it from anothe= r=20 console :( (this also means that I cannot CVS atm) If I need to raise a PR or something else for this please let me know, as I= am=20 new to this process. If you require more information please let me know as= =20 well, I am happy to provide. Kind regards, Patrick Gelsema __________________________________ System Details: mainboard: Asus M2N processor: AMD Athlon 64X2 4800+ memory: 2GB chipset: NVidia MCP6 logs read from console when running: 7.0-Current-200704 ahd0: <Adaptec 39320D Ultra320 SCSI adapter> port 0xe800-0xe8ff,0xe400-0xe4= ff=20 mem 0xdd7fe000-0xdd7fffff irq 16 at devuce 10.0 on pci1 ahd0: [GIANT-LOCKED] ahd0: [ITHREAD] aic7902: Ultra320 Wide Channel A, SCSI Id=3D7, PCI 33 or 66Mhz, 512 SCBs da0 at ahd0 bus 0 target 4 lun 0 da0: <SEAGATE ST336753LW HPS2> Fixed Direct Access SCSI-3 device da0: 160.000MB/s transfers (80.000MHz DT, offset 63, 16 bit) da0: Command Queueing Enabled da0: 34732MB (71132960 512 byte sectors: 255H 63S/T 4427C) logs read from console when running: 6.2 Release #0 ahd0: <Adaptec 39320D Ultra320 SCSI adapter> port 0xe800-0xe8ff,0xe400-0xe4= ff=20 mem 0xdd7fe000-0xdd7fffff irq 16 at devuce 10.0 on pci1 ahd0: [GIANT-LOCKED] ahd0: [ITHREAD] aic7902: Ultra320 Wide Channel A, SCSI Id=3D7, PCI 33 or 66Mhz, 512 SCBs da0 at ahd0 bus 0 target 4 lun 0 da0: <SEAGATE ST336753LW HPS2> Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz DT, offset 63, 16 bit), Tagged Queue= ing=20 Enabled da0: 34732MB (71132960 512 byte sectors: 255H 63S/T 4427C) --nextPart2669217.BftJGTctvS Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQBGI+DhKz+4Gcg+TBERApzjAJ9KUQZWgpcRDTXxSBJUxK/UYWMyuACgxfvO dEntQFGq52hVCbGLsLs6DtQ= =cgWW -----END PGP SIGNATURE----- --nextPart2669217.BftJGTctvS--
