If there are lot of files,its definitely going to utilize more cpu
I believe the below form is more efficient
and if you don't want this script to affect/trouble some other realtime process you could set less priority to 'find' command using 'nice'
Good morning,
I need some help figuring out what's eating up my cpu. My application can't get enough cpu to do its job. this is a sunfire V440 2CPU's at 1/593 GHZ with 8GB of memory. In the morning hours the box is at less than 3%. I can't figure out what else is using the CPU. We use foglight and... (2 Replies)

Currently, i have been told that eventhough there are no files to process, the CPU utilization is very high. An independent evaluation by advisory specialist has found this script does... (2 Replies)
Hi,
I am working on a solaris app processor and the vsh goes high from time to time. I have executed various ps commands and switches and have found that it looks like the rlogind daemon is terminating vsh and not cleaning up after itself. There are also something like 10 zombies hanging around... (2 Replies)

rtprio
RTPRIO(2) BSD System Calls Manual RTPRIO(2)NAME
rtprio -- examine or modify a process realtime or idle priority
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/rtprio.h>
int
rtprio(int function, pid_t pid, struct rtprio *rtp);
DESCRIPTION
The rtprio() system call is used to lookup or change the realtime or idle priority of a process.
The function argument specifies the operation to be performed. RTP_LOOKUP to lookup the current priority, and RTP_SET to set the priority.
The pid argument specifies the process to be used, 0 for the current process.
The *rtp argument is a pointer to a struct rtprio which is used to specify the priority and priority type. This structure has the following
form:
struct rtprio {
u_short type;
u_short prio;
};
The value of the type field may be RTP_PRIO_REALTIME for realtime priorities, RTP_PRIO_NORMAL for normal priorities, and RTP_PRIO_IDLE for
idle priorities. The priority specified by the prio field ranges between 0 and RTP_PRIO_MAX (usually 31). 0 is the highest possible prior-
ity.
Realtime and idle priority is inherited through fork() and exec().
A realtime process can only be preempted by a process of equal or higher priority, or by an interrupt; idle priority processes will run only
when no other real/normal priority process is runnable. Higher real/idle priority processes preempt lower real/idle priority processes.
Processes of equal real/idle priority are run round-robin.
RETURN VALUES
The rtprio() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate
the error.
ERRORS
The rtprio() system call will fail if
[EINVAL] The specified prio was out of range.
[EPERM] The calling process is not allowed to set the realtime priority. Only root is allowed to change the realtime priority of
any process, and non-root may only change the idle priority of the current process.
[ESRCH] The specified process was not found.
