load average
we have an unix system which has
load average normally about 20.

but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?

while running that batch idle cpu time is about %60-65
while not running idle cpu time is about %70-80

how can i check swap status to determine if there is
a bottleneck or not?

tload

TLOAD(1)							Linux User's Manual							  TLOAD(1)

NAME

       tload - graphic representation of system load average

SYNOPSIS

       tload [-V] [-s scale] [ -d delay ] [tty]

DESCRIPTION

       tload prints a graph of the current system load average to the specified tty (or the tty of the tload process if none is specified).

   Options
       The -s scale option allows a vertical scale to be specified for the display (in characters between graph ticks); thus, a smaller value rep-
       resents a larger scale, and vice versa.

       The -d delay sets the delay between graph updates in seconds.

FILES

       /proc/loadavg load average information

SEE ALSO

       ps(1), top(1), uptime(1), w(1)

BUGS

       The -d delay option sets the time argument for an alarm(2); if -d 0 is specified, the alarm is set to 0, which will never send the  SIGALRM
       and update the display.
