Open port 443 = slower traffic?

[Gunslinger08]

Has anyone ever experienced this? We started allowing SSL traffic into a server, and the network performance has gone down quite a bit. I don't know what could be causing this, beyond a virus or spyware that operates on port 443. Any ideas?

Is this server behind a firewall or is it inside a private network? Port 443 is HTTPS. Do you have any HTTPS services running?

 

[spidey07]

is it just ssl performance or overall performance?

check the cpu on the server. ssl can kill a server. That's why a lot of time you offload it to hardware devices that do the encryption.

HTTPS opens a persistant connection to the web server where as HTTP does not. This adds additional overhead to the server.
