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

cygwin, my midnight commander started to get very laggy - starting mc,
any change of directory or exiting from finding files (to refresh list

I have no idea what could be the reason for these hiccups. MC normally

* cygserver is installed
two ideas to try:

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
