Packets journey takes longer on Site-2-Site with SSL-VPN?

tekuton
We are looking on a time-consuming behaviour between two locations when using SSL-VPN for a S2S between a Astaro v8 and v9.
Calling a webpage off a server which is behind the v8/SSL-VPN S2S takes more or less 400ms. When calling a webpage from a server which is behind a third Astaro on v9 and S2S is via IPSEC,
we get 200ms. When tracing to the webserver on the SSL-VPN S2S we see a IP from the SSL-User pool as the second hop. When tracing over the IPSEC tunnel we find the IP of one of the endpoints and the webserver as one would have expected it.
So, is it normal when using S2S with SSL-VPN that it takes that long?

thanks and regards

    To speed up an SSL VPN, change the protocol to UDP on the 'Settings' tab and then re-download the client and install it on the other UTM.  It still won't be as fast as IPsec, but it should be much faster.
