[mythtv-users] Slightly OT: hdparm results

[Wood, Mike]

Guys & Girls,

I'm trying to make sure my hard drive is performing optimally for MythTV so
I just wanted to bounce these numbers off you to see if they look ok:

[root at MythTV sysconfig]# hdparm -t /dev/hda
/dev/hda:
 Timing buffered disk reads:  64 MB in  4.23 seconds = 15.13 MB/sec

[root at MythTV sysconfig]# hdparm -T /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.85 seconds =150.59 MB/sec

[root at MythTV sysconfig]# hdparm /dev/hda
/dev/hda:
 multcount    = 16 (on)
 IO_support   =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 7297/255/63, sectors = 117231408, start = 0


Does this look ok?  Seems strange to me that the disk reads would be sooooo
much slower than the cache reads.  This is a 60gb/7200rpm Seagate drive in a
RH9 machine, with a PIII 667mhz & 384mb of RAM.  Oh, and the file system is
EXT3.

Thanks, Mike
