Hi,
 
Marco, cgf, Thanks for the reply.
 
I don't use bash-completion.
$ cygcheck -cd bash-completion
Cygwin Package Information
Package              Version
$
I do use symantec antivirus which is in the BLODA list. I disabled it and observed a little performance improvement.

But not dramatically. Other PCs I have also have symantec antivirus and no problem. Also in the problem PC symantec antivirus 
had been installed from the beginning and no performance issue was seen before. So I doubt symantec is the main contributor 
to the command delay. But since no other systems with the same dll level do no see the problem, I think it is possible there 
may be other software that interfares cygwin's work. Is there any good way to find a specific BLODA that is having main effect
to my PC?
 
Regards,
Yuta
