IPsec speed test encryption algorithms

I configured the connection between two computers through two Microtics (951Ui-2HnD) using L2TP / IPsec.
But low speed of about 27 Mbit / s. :frowning:
Settings for channel: AES-128-CBC without HMAC (no md5, no sha1 …) MTU: 1400.
may need to use different values to a higher speed?

How in Mikrotik to test the speed of encryption algorithms? there is an analogue console commands like openSSL?

openssl speed aes-128-cbc aes-256-cbc aes-128-ctr aes-256-ctr aes-128-gcm aes-256-gcm camellia-128-cbc camellia-256-cbc

Those routers do not have hardware accelerated IPsec.
Use RB750Gr3 instead and it will fly!

To measure speed, do not use a tool on the router itself. Transfer data from a separate system located at each end.
