Single pass parallel processing

[Sarou22]

Hello, I don't understand why it is said that the single pass parallel processing performs operations once per packet.
What does this mean?

Firstly, the single-pass software performs operations once per package.

Thanks

Either of these will go over the benefits and how this actually functions.

Hello,

After Reading the documents, I still don't understand why WE Say thay the single pass software performs operations once per packet.  "As a packet is processed, networking functions, policy lookup, application identification and decoding, and signature matching for any and all threats and content are all performed just once. "

This means, for example, that for a package we'll check whether it matches a policy and at the same time decode the application?

Why do we only need to do this once?

@Sarou22 Yes it processes all the inspections in parallel other than waiting for one inspection to finish and start the second inspection.
