You're running NT4SP5, right?
Joe wrote on cygwin-developers: "On an NT machine running SP5, an "ls -l" on /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services returns in 0.25 seconds now. Without the patch, I killed it after 7 minutes because I got tired of waiting for it to finish." The differences is that you use ls -lR. I have debugged a slowdown problem with /proc/registry back in June 2002: http://sources.redhat.com/ml/cygwin/2002-06/msg00103.html http://sources.redhat.com/ml/cygwin/2002-06/msg00188.html I don't remember anyone fixing this so I guess this is what causes the slowdown on your machine.
