| |
I have just built a server using an ASUS A7N8X deluxe Motherboard with and AMD 2500. The motherboard includes the Silicon Image Serial ATA system. Attached are two Maxtor 120Gig serial ATA drives.
I have compiled a new kernel (2.4.21) which includes support for the Sil3112.
The machine boots but have very slow drive access. Can someone please tell me if there are some settings to improve drive throughput?
Here are the details:
hdparm -Tt /dev/hdg /dev/hdg: Timing buffer-cache reads: 1148 MB in 2.00 seconds = 574.00 MB/sec Timing buffered disk reads: 4 MB in 3.02 seconds = 1.32 MB/sec
For comparison here is the results from an ancient AMD K6-200Mhz box:
/dev/hdb: Timing buffer-cache reads: 128 MB in 2.73 seconds = 46.89 MB/sec Timing buffered disk reads: 64 MB in 7.58 seconds = 8.44 MB/sec
