Our USG 310 ist very slow if we have SSL inspection and content filter on.

We think that the problem ist the content filter. If we stop the content filter the sites open in 3-5 seconds, with filter > 18 seconds. The CPU workload is < 20%. We have 40 workstations behind the USG. The Firmware is V4.73(AAPJ.0) / 2022-11-18 09:07:22

Is here someone who know this problem?

    At the moment I use ECDSA-RSA-1024. I had testet the RSA 1024, but there was no difference.

    Hi @weite,

    Can you send startup configuration to me in PM.

    I would like to conduct a lab test based on your configuration file to see if it have slow issue.
