Internet speed issues when connected to Mobile Connect — iOS 11.2.3

I've been using Mobile Connect to connect to one of my clients server for about 3 years and everything was working perfectly until about 1-2 months ago, when I noticed that my upload speed got really slow whenever I'm connected to their server.

The SonicWall Mobile Connect version I have installed on my machine is the latest version (Version 5.0.7) and my iOS version is 11.2.3 (Big Sur).

Speed test when connected to Mobile Connect:

DOWNLOAD Mbps 7.66

UPLOAD Mbps 4.94

Speed test when disconnected to Mobile Connect:

DOWNLOAD Mbps 82.94

UPLOAD Mbps 76.20

Now, I do expect a difference in speed when connected to the VPN, but the difference I'm seeing now is huge. Is there anything I can do on my end to prevent this huge decrease in speed?

    Thank you for visiting SonicWall Community.

    Are you using split tunnel or tunnel all mode SSLVPN? Any specific configuration change happened on the SonicWall? Is this issue seen on SMA box or Firewall box?
