VPN Tunneling Default Bandwidth Allocation per User

[patander]

One of our customers complaint about poor speedtest result over a Pulse VPN connection.

While investigating the issue, I ran some tests myself and noticed that apparently bandwidth is limited on a per User basis in the following manner:

For example, being connected to a PSA3000-V, using SSL transport mode, I got maximum download and upload speeds of around 40 Mbps.

This was after hours with only 7 users in total connected to this PCS and the speeds I achieved amount to roughly the maximum throughput offered by the PCS in SSL mode (286 Mbps) divided by the number of users connected.

At another time, with 13 users connected, the speed was around 20 Mbps.

As expected, when I switch to ESP transport mode, the download and upload speeds nearly double.

Has anyone else noticed this and/or can point me to a document where this (default?) behaviour is described in detail? We have no bandwidth management configuration on this PCS. Or am I completely on the wrong track?

Thanks

Patrick

i can confirm that ESP is expected to be noticeably faster than SSL. Unfortunately, no, i am not aware of this being outlined anywhere. there is no bandwidth configuration by default on the system; that speed is more than i would expect on ssl.

I noticed this on <9.1.13 (Client & Server) with newest Version it is getting better, nearby connection speed of user. But newer Version has some problems with virtual adapters (Microsoft)... What version do you use?
