Running this version of Cygwin:

CYGWIN_NT-6.1-WOW64 JJR 1.7.7(0.230/5/3) 2010-08-31 09:58 i686 Cygwin

I have a directory with 753 files.

"ls -lrt" (directory in reverse time order) takes forever (well, over
2 minutes):

0.062u 0.264s 2:18.31 0.2%      0+0k 0+0io 2822pf+0w

A straight "ls" takes under 1/10 second:

0.000u 0.046s 0:00.08 50.0%     0+0k 0+0io 2572pf+0w

This is a 1.5TB SATA drive in a Intel Q6600 computer with 4GB of RAM.

This seems to be a recent problem.  Any idea what it might be?

Thanks - Jim
