Hi all, I have the a problem with my adaptec aic7895p Ultra scsi...blabla... with IBM DCAS-34330W... and the problem is that the scsi performance is very slow... I'm untar-ing a 64kbyte file for 10seconds !!! and deleting the untar-ed files for 7 seconds !!! I tryed with setting the 'camcontrol tags da0 -N 64' but nothing did change. Here is the dmesg: ahc0: <Adaptec aic7895 Ultra SCSI adapter> port 0xd400-0xd4ff mem 0xebfee000-0xebfeefff irq 16 at device 9.0 on pci0 aic7895C: Ultra Wide Channel A, SCSI Id=7, 32/255 SCBs ... da0 at ahc0 bus 0 target 6 lun 0 da0: <IBM DCAS-34330W S65A> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 8, 16bit) da0: 4134MB (8467200 512 byte sectors: 255H 63S/T 527C) Thanks in advance, Kiril Tsvetkov, bg.
