This is for v3 which forces SSL by default as opposed to v2 which does not.

Hey Fred,

SSL/HTTPS is only enabled by default on the admin section. You can still use regular HTTP on the agent interface.

I figured out a way to speed things up significantly by enabling keepalive and disabling slower cyphers in apache.

KeepAlive On

SSLHonorCipherOrder On
SSLCipherSuite ALL:!ADH:!EXP:!LOW:!RC2:!3DES:!SEED:!RC4:+HIGH:+MEDIUM

Is your server behind a firewall? We haven't encountered any speed issues using HTTPS over the internet (server is on a public IP).

The server is not behind a firewall. No iptables. Nothing. It's a direct connection to a public static IP.

We have seen this with other self signed software that forces SSL as well. Elastix in particular. Disabling SSL fixes it. Since that is much more difficult in Gotoautodial we use the other method explained above. It's night and day difference 100% reproducible across multiple installations.

If you run the server on a hosted VPS that is several hops and more than just a few ms away from you over the internet you will see it. You will not see it on a LAN or nearby server over a fast WAN.

We are accessing most of our servers over the internet (some on dedicated hardware and some on VPS with more than 180ms latency). Delay is acceptable compared to plain HTTP. Nothing close to what you are experiencing.

With SSL enabled the Web GUI is very slow when done over WAN/Internet

Access is almost the same as with our servers signed with EssentialSSL and self-signed ones. We can't really notice any difference.

I'm willing to bet you have Apache set to keepalive on. That makes all the difference in the world. Using lower overhead ciphers and enable caching for static files improves things a bit more.
