Strange performance problem < Help needed

[einbert]

Hi,

I have a rather strange problem certainly due to some misconfiguration somewhere... When I use a sort command on a file I have a result 15 seconds later when running as root; but when the same command is used with another user I have still no result 30 minutes later. What I have checked so far:

• Nice value and priority (checked via top) are the same
• The file is readable by the test user and he has write access in the folder (as the result of the sort is written in another file)
• No limitation on the user (checked with ulimit)

The sort is done on a 300MB text file.

Has anybody an idea where the problem could be?

Thanks a lot for your help.

Chris

Ok, I found the problem... And the problem is due to a missing environment variable, i.e if I set LC_ALL="C" , everything works as expected with the sort command. More on this on http://pankaj-k.net/weblog/2007/08/i...rt_broken.html . By the way, the problem was on RHEL5 with coreutils-5.97-12.1.el5.
