Slow Copy(CP) performance

Hi all

We have got issues with copying a 2.6 GB file from one folder to another folder.
Well, this is not the first issue we are having on the box currently, i will try to explain everything we have done from the past 2 days.

We got a message 2 days back saying that our Production is 98% full (disk space). So we started compressing all the old files, moved half of them to a backup server, and compressed the remaining on our server. By doing this we effectively bought down the disk space occupancy to 79%.

Now today morning when i tried to run my process, the copying of a 2.6 GB file from folder A to folder B took ages. The SA checked the CPU utilization and told me that it was HIGH. i went ahead and killed some orphaned processes, to bring the CPU Utilization to 20%. Now, when there is high activity the CPU utilization varies between 20-35%.

Even after improving the CPU Utilization, the copy of file is still painfully slow.

Any guesses on what might have gone wrong ??? Smilie

Let me know if i need to elaborate more

Thanks
Sri

NAME

       utild - System-utilization collection daemon

SYNOPSIS

DESCRIPTION

       is  a  lightweight daemon that records system-utilization data on a 5-minute interval.  System-utilization data includes CPU, memory, disk,
       and network data.  is installed as part of the software, which also contains a WBEM provider that is the interface to the data collected by
       stores  up  to  30 days worth of utilization data and consumes minimal system resources.  The total disk space consumed by these data files
       should not exceed 20 megabytes in the default installation.  is respawned if it is killed, due to the following entry in /etc/inittab:

WARNINGS

       Removing the removes any historical data that has been collected by as well as prevents and from  functioning  properly.   To  disable  the
       software can be removed with the following command (see swremove(1M)):

FILES

       WBEM mof files documenting the class schema for retrieving utilization data
			   collected by
       Data and configuration files.  These files contain the definitions of
			   all	workloads  created  on	the system, and up to 30 days of collected utilization data.  To ensure continuity of data
			   collection and prevent loss of workload definitions, HP recommends including this directory in daily backups.
