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
