CSAF ingestion performance

[ctron]

I think that the CSAF ingestion performance is problematic:

I think we can't discard the latency involved in the process

with this script to fake internet connection for tests , the Time remaining: 3 hours jumped to Time remaining: 5 hours

➜  bin cat f_my_internet
#!/bin/bash
sudo tc qdisc add dev **the-interface-here** root tbf rate 1000bps burst 50kbit latency 300ms

I found a warning on csaf-walker

This is being used in the app:

➜  trustify git:(main) rg "Fetcher\:\:new"
modules/importer/src/runner/sbom/mod.rs
62:            Fetcher::new(FetcherOptions::new().retries(fetch_retries.unwrap_or_default())).await?,

modules/importer/src/runner/csaf/mod.rs
57:            Fetcher::new(FetcherOptions::new().retries(fetch_retries.unwrap_or_default())).await?;

Although I don't think the new function is causing problems as apparently it is being called just one time in the app
inside of this functioin: pub async fn run_once_csaf(

• I'm not saying csaf-walker is causing problems
• I'm investigating... because apparently tokio is going wild and I'm looking for sync functions in different places...
