system load spike

[Kent Tong <kent@cpttm.org.mo>]

Hi,

I am using a shell script to perform backup. Whenever it is launched, the
system load average
reaches 3-5 regularly. I am already launching it script using "nice -n 19".
The script is using
find, cpio and gzip. They should automatically inherit the nice value of 19.
I am already using
"gzip -1" so that it uses the least CPU. It is possible that the bottleneck
is I/O, not CPU.

Is there any way to reduce the system load?

Thanks!
