Check Point Endpoint remote access VPN Slow Network Performance

We are experiencing slow network performance when connected via Check Point Remote Access VPN.

We have Cloudguard as the VPN gateway, VPN protocol IKEV2, Endpoint remote access vpn client version is E89.25

My R82.10 Gateway is using the following settings for Remote Access VPN:

Phase 1: AES-256. SHA256, DH Group 14
Phase 2: AES-256. SHA256

We have tested network speed from an AWS EC2 instance to the Internet using the same CloudGuard gateway and AWS Internet Gateway. The throughput is approximately 1 Gbps.

This indicates that the CloudGuard gateway and AWS Internet Gateway are unlikely to be the primary bottleneck.

The performance issue appears to be specific to traffic traversing the Remote access vpn

We have also confirmed that AES-NI is supported on the gateway:

fw ctl get int AESNI_is_supported

AESNI_is_supported = 1

SecureXL is also enabled and processing traffic. Current statistics show:
