During testing I have found that vpn is not the only issue anymore. We get really poor performance through the MX67 for a lot of things but not online speedtests 🙂

But with Breaking Point we're pushing just over 200Mbps on an Enterprise license, and about 175Mbps with an Advanced license through a VPN on an MX67 running 14.34. Do you run that vpn to another Meraki mx? My customer runs the vpn to a Sophos FW, but that one pushes 3-400 Mbit through other tunnels when tested...

I see the same issue outside a vpn tunnel as well. Just running iPerf on the inside of the MX67 accessing a server that sits on 1 Gbit/s Internet cuts performance per stream from 600 Mbits/s down to 50 Mbits/s.

Tested on 14.32, 14.34 and 15.10. same results. Also verified with an MX64 and an MX65. None of them share the same issue. They give full speed to just one stream with iPerf.

Hi! I've got a customer with a series of MX65 and one MX67. They are experiencing poor vpn s-2-s performance to a thirdparty vpn concentrator. We started troubleshooting by doing standard online speedtests and could find no problems. With iPerf (and Windows file transfers) we get very slow performance, around 20-30 Mbit/s when we are expecting close to 100 Mbit/s on the vpn (ISP link is capable of 250 Mbit/s). When using iperf to an external server over tcp with standard settings we get a peak of around 50 Mbit/s and if I use parallell streams I immediately get the expected performance (if I use enough streams to fill the Internet link, at least 5 streams). Connecting the client outside the MX67 gets the expected results, (around 250 Mbit/s on one stream). Has anyone else seen this kind of behaviour? I have also tested with another MX67 in our office and come up with similar differences between inside and outside. Here at our office we have 1 Gbit/s and the MX67 has a throughput on speedtest of 450 Mbit/s but iPerf only reaches 50 Mbit/s on one stream. Using 16 parallell streams will reach 450 Mbit/s.
