Very slow unix cmds on Windows 10

[hackhowtofaq]

I am adding this issue, because is difficult to locate this valuable information!

In my case, I had git installed separately, so cmder was using my installed version of git+all other Linux ({GIT path}/usr/bin) commands (ls for example).

I tried all workarounds from the numerous issues with no luck.

The craziest issue I encounter: sometimes all linux cmds were executing really fast with degradation to very slow execution (a simple ls more than 10sec!)

What solved the problem?
Both @lunyx on #993 and @davidnero on #763 are giving the correct solution.

cd to where your Git app folder is stored
i.e. c:\Users\myname\AppData\Local\Programs\Git
and execute
mkpasswd -l -c > passwd
mkgroup -l -c > group

then check that nsswitch.conf on i.e. c:\Users\myname\AppData\Local\Programs\Git\etc
is

# Begin /etc/nsswitch.conf

passwd: files db 
group: files # db

db_enum: cache builtin

db_home: env windows cygwin desc
db_shell: env windows # cygwin desc
db_gecos: env # cygwin desc

# End /etc/nsswitch.conf
