Re: Midnight Commander is very slow when starting and changing directories

I'm using midnight commander with Cygwin 64 bit on Windows 10 64 bit.

After moving to a new machine and a clean reinstall of windows and
cygwin, my midnight commander started to get very laggy - starting mc,
any change of directory or exiting from finding files (to refresh list
of files in the two panes) takes long seconds. Restarting doesn't

I have no idea what could be the reason for these hiccups. MC normally
works fine: arrow presses work well, viewing and editing is instant,
but this one thing takes up to 10 seconds - changing directories.
Searching in files has a similar lag, but only once (ie not in every
`chdir` it could have done). In non-mc cygwin usage this issue doesn't

The task manager doesn't show any abnormally high CPU or memory usage
on any process. I have `cygserver` running, using `bash` as my shell
and have no fancy `PS1` settings, my `$CYGWIN` is only

My environment:
* Windows 10 pro 64 bit, up to date
* Not connected to a domain, no network drives
* No anti virus software apart from the one built in Windows
* Two hard drives (system on SSD (C:), D: is a SSHD), quite a few
directory junctions from C: to C:, no loops
* I'm usually using fatty as the terminal, but mintty has the same issues
* GNU Midnight Commander 4.8.17
* cygserver is installed

two ideas to try:

- update cygwin package as 2.5.2 versus the 2.5.1 that you are running
  has few bug fixes that could change the responsiveness.
  (unlike to work but worth to try)

- disable the windows anti virus.
  Experience in the past with Windows Defender were disappointing
