Slow cygwin executable start up

[Cary Lewis]

I am experiencing a problem with Cygwin on my Dell 7590.

There is a multi-second delay when starting a cygwin program from a mintty
window, but only the first time that a program is run.

E.g. if  run openssl version, then sometimes there is a delay before
anything is outputted.

If I run the command again, there is no delay.

I ran a test with strace, and I believe the delay occurs during the initial
loading of the cygwin dlls:

--- Process 6232 created
--- Process 6232 loaded C:\Windows\System32\ntdll.dll at 00007ffe3b4c0000
--- Process 6232 loaded C:\Windows\System32\kernel32.dll at 00007ffe3a660000

--- Process 6232 loaded C:\cygwin64\bin\cygwin1.dll at 0000000000da0000

Can anyone suggest why this is happening?

The version of cygwin is:

$ uname -r
3.2.0(0.340/5/3)

By the way, I don't see this on my older PC, it's version of cygwin is:
3.1.7(0.340/5/3)

I don't really want to upgrade my older PC to the latest cygwin to test if
the 3.2 version is the culprit or not.

I also upgraded from windows 10 to windows 11 on the PC experiencing the
slow start issue, and that didn't have any effect on the problem.
