[SLUG] Sharing SATA disk

[Rod Butcher]

I'm running 2.6.7 kernel with low-latency patches for audio file 
processing. It seems to me that when 2 separate apps are writing to the 
SATA hard disk (e.g. copy contents from IDE CDRom and 56k internet file 
download) the CD file copy slows to a crawl - i.e. the total time taken 
to write data is far more than just the sum of the 2 processes).  Is 
this a consequence of low-latency patches ?
Internet download at 56k won't be writing very fast to the disk, and 
copy from a CDROM on the separate IDE channel should only take a few 
seconds rather than minutes for 650 meg. ???
thanks
Rod
