Hi! I've make a script that gets a list of 200 Ip's and calls another script once per ip in a infinite loop with a pause of 10 seconds. So It calls over 200 times every 10 seconds the second script (that makes a fping). But this cause a load average of 30. I've been reading about this and I undestand that the load average is high because there are a lot of processes (the second script I guess) waiting to be executed. My server has a good performance so, is possible that this high load will become a problem in the future or is it a normal behavior when you run such scripts as I do?

we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy

how can we explain this situation?

Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

uptime
UPTIME(1) User Commands UPTIME(1)NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
