URGENT! Intrusion Prevention module causes a severe slowdown of download speed

Hello all,

Reproducable on 3 laptops, 2 with Windows 11 x64 and 1 with Windows 7 x64.

Browsers used: Edge and Chrome.

It started with N360 22.23.10.10 and it continues with 22.24.1.6 version.

I have a 500/50 Mbps bandwidth plan from my ISP (FTTH).

Whenever I run a speedtest  at: Speedtest by Ookla - The Global Broadband Speed Test  

                                                      https://fiber.google.com/speedtest

                                                      COSMOTE MySpeedTest  (My ISP's speedtest site)

with Intrusion Prevention enabled I'm getting those:

 

 


As soon as I open N360 then go to: Firewall / Intrusion & Browser Protection and TURN OFF the Intrusion Prevention button

I'm getting those below:

 

The difference is HUGE!!!!!!!

Same when I d/l a file from the browsers, with Intrusion Prevention ON the d/l speed is about 42-45 MB/sec now with Intrusion Prevention OFF I see constant d/l speed of 65 MB/sec.

All other options like, turn off Browser Protection, deactivate all IPS signatures, add app URL's for exclusion do not work.

Only the Intrusion Prevention toggle set to OFF solves the problem.

Ping is not affected on both cases:

However, when I run a Speedtest from the standalone app for Windows, speed is not affected.

This needs to be fixed YESTERDAY!!!
