SSL Inspection slows down the connection speed
Model: USG210
Hi, when i enable SSL inspection the connection is very slow.
Average speed without SSL is 45Mbit download/ 5Mbit upload.
With SSL 20Mbit/400Kbit.
The connection has frequent interruptions, especially in upload. How can I solve the problem?

Hi @ComMon
After enabled SSL inspection function, device will do certificate key exchange between HTTPS server and client. This function will decrease system resource.
Currently we are working on SSL inspection performance enhancement in future firmware.

1- USG 200 V4.62(ABUI.0) / 2021-01-19 11:22:24
2- Speed test is done with standard online speed test pages like Spectrum internet speed test but that isn't the issue. The issue is that it takes forever for the pages to load under SSL inspection
3- The throughput doesn't change. That portion is fine0 -
