Really slow site-to-site VPN

[mvalpreda]

MX67 with (at least) 100mbit connections at 4 different locations. Noticed getting files off shares at the data center going slow, so did and iPerf3 test. Never got over 12mbit and typically <10mbit. Running MX 17.10.2 everywhere. Dashboard speed and other speed tests are showing full circuit speed. 

Had a case open for over a month and not getting anywhere. Wonder if anyone has any suggestions.

Have you tried to downgrade to 16.16.X ? Lots of people complaning about slow speed since 17.X

What licence and feature do you have on ? IPS IDS ?

I just asked the case owner about that. See if I can get to 16.x all around.

Advanced Security. IPS/IDS is on....but this is over site-to-site. Internet speed is not an issue at all. Get full circuit speed when doing a test from any of the locations.
