Leopard 10.5.6: netstat, lsof -i, traceroute slow

Question

Did anyone else notice that netstat -a, lsof -i, traceroute and establishing connection to another Mac take exceedingly long after 10.5.6 update?
netstat -a can take up to 3 - 5 min on my Mac Pro, whereas it used to list all connections in a second or two before?

Answer 1

Since I installed the combo update my overall performance is horrible!
My specs are the same as yours, therefore I'm responiding.
Almost everything is slow, even moving windows around is jumpy sometimes.
For DNS resultion I run a local named installation as a forwarding/caching installation. After connections are established, everything is fine, but something is really messed up.
It's not the response time of my DNS server, that is perfectly fine for cached queries. It's the initial TCP connections that take ages!
I already installed the combo update twice, my file permissions are totally fine.
Everything seems to be OK as far as the installation goes, but still all of my applications that do any kind of networking are somehow screwed up ...
My post is no help at all, but I read your post and feel your pain.
Please find below that CONNECTING takes more than a second,
the whole request takes nearly 2.5 seconds.
No network activity while I am doing this!!!
