Slow IPsec - CCR-1036<->UBNT PowerBridgeM10<->CCR-1036

Hi, I have a problem with the throughput IPsec connections between CCR-1036 through POWERBRIDGE M10. When I am in the configuration of IPsec Policy IPsec Protocols set esp, throughput is only around 10 Mbits / s, when I switch on the ah, throughput have around 90 Mbits / s. I need to have an encrypted connection, what’s the problem? OS version is 6.27
