You mean grisu at db.debian.org?
The slow verification should only happen the first ti e you do this.
He has a lot of signature on his key and the Web of Trust has to be
done (yes, I know that it is far too slow and I have plans to rewrite
that whole thing). This takes a lot of time.
Since 1.0.5 key signature are checked everytime the key is used; this
makes it really slow. Try that hint from the NEWS file:
* The verification status of self-signatures are now cached. To
increase the speed of key list operations for existing keys you
can do the following in your GnuPG homedir (~/.gnupg):
$ cp pubring.gpg pubring.gpg.save && $ gpg --export-all >x && \
rm pubring.gpg && gpg --import x
Only v4 keys (i.e not the old RSA keys) benefit from this caching.

Another reason might be that there is one key signature done with an
ElGamal signing key - that is much slower than DSA or RSA.
