Hello! I think i can get much more speed during l2tp connection from home to my office network.
There are an screenshots which shows, speed at my home wireless network is ~65 Mbit\sec.
In the office network speed is 200Mbit\sec.
In Office Zywall 110 we have VPN Server connection via L2tp\Ipsec (Ikev2) and 3 Algorythms of Encryption Phase 2
Then i test speed between office server and my home laptop via iperf3
Home laptop:
Office server:
As you can see , real speed is very slow , and it shows in real tests, example during file copying from server to home laptop etc.
Please help guys, what i can check or change in my settings to increase speed?

Hi @DmitryYudin,
It is single session by default.
Can you test it again with multiple sessions. Performance would be better than single session.

Hi @DmitryYudin,
Comparing to single session, multiple session is better than single session. it is around 5x better than before. Because single session runs in single processor core to process traffic.

HI @DmitryYudinYes...there is no speed...
I checked my l2tp connection speed and this is what I got:
250Mbit\sec home channel
100Mbit\sec channels in all offices
USG 1000 25-30Mbit\sec
Zywall 310 50-55Mbit\sec
FLEX 700 95Mbit\sec

Hi! It means , it is ok? And i have no problem with real speed ?

This is your post in 2020, is the problem back again?
Try to establish a connection from your phone to your USD 110 gateway? will the connection speed be as low?
I have an ipsec tunnel between Zywall 310 and USG20-VPN, data transfer rate 5.5-7.5 MB/s (CPU USG20-PN is 100% loaded), the speed of both channels is 100Mbit\sec
