--list-sigs, --check-sigs and --list-keys

[Sascha Kiefer]

Hi.

1. is it true that --check-sigs and --list-sigs have pretty much the 
same output: --check-sigs just adds the signature information?
I used the following syntax:

--fixed-list-mode --with-colons --list-keys --with-fingerprint 
--with-fingerprint
--fixed-list-mode --with-colons --check-sigs --with-fingerprint 
--with-fingerprint

2. is there a significant performance difference between --check-sigs 
and --list-sigs?

Thanks for help.
