Speed Test Issues with DPI Enabled on SonicWall NSA 4700 nsa

Hope everyone doing well here,

I am currently using a SonicWall NSA 4700 NSA with enabled. Recently, I have encountered a strange issue during speed tests. When I initiate the speed test, the download speed starts at around 999 Mbps but then gradually decreases to approximately 80-90 Mbps. The same behavior is observed with the upload speed.

Interestingly, when I disable DPI, the speed test results are consistent and perform as expected.

Has anyone in the community experienced a similar issue? I would appreciate any guidance on diagnosing and resolving this problem.
