GNU 'ls' had some performance improvements in this area recently, so
perhaps all you need is an upgrade.
Which version of GNU ls are you talking about? (Type "ls --version".)
Which version of Solaris? ("uname -a" should tell you.)
What kind of Solaris filesystem? ("df -k .; mount" should tell you.)
Which locale? (The "locale" command should tell you.)
I can't reproduce the problem with coreutils 5.2.1 on Solaris 8 sparc
in a directory with 39697 files; the directory is NFS-mounted from a
Network Appliance box of unknown vintage.
