Re: TERRIBLE sort performance in RedHat 9.0

[Mike Westall]

Thanks,  I'll try the official code out.  

the LC_ALL=C appeared to make no diff.

Its not a critical problem to me since the RH 7.2 sort
works just fine on the RH 9.0 systems.

RH-9.0 has been out so long I was amazed that a google
search of for redhat sort performance yielded no hits.
Maybe no one sorts anymore!

top shows 100% CPU util and almost no time spent in
kernel state so it doesn't appear that RH sort has decided
that 4 MB files must be sorted using auxilliary disk
files.
