nostr:npub1drvpzev3syqt0kjrls50050uzf25gehpz9vgdw08hvex7e0vgfeq0eseet have you ever seen any behavior like this with LMDB? I don’t know if it would effect the rust Nostr but bindings or not.

Awesome! Unfortunately the website is not on github, but I think nostr:npub1m0sxqk5uwvtjhtt4yw3j0v3k6402fd35aq8832gp8kmer78atvkq9vgcru is best to update it. Can you add the new snippet?

hey nostr:npub1drvpzev3syqt0kjrls50050uzf25gehpz9vgdw08hvex7e0vgfeq0eseet, rust-nostr.org and rust-nostr.github.io doesn't seem to work anymore.

Hey nostr:nprofile1qqsx3kq3vkgczq9hmfplc28h687py42yvms3zkyxh8nmkvn0vhkyyuspz4mhxue69uhkummnw3ezummcw3ezuer9wchsz9thwden5te0wfjkccte9ejxzmt4wvhxjme0qy88wumn8ghj7mn0wvhxcmmv9u0uehfp and #rust-nostr fans, can you enlighten me please:

When I am calculating my Web of Trust I do the following:

0. Create client with outbox model enabled

1. Get my follows, mutes, reports in one fetch call

2. Get follows, mutes, reports of my follows in another fetch call, using an authors filter that has all follows in it

3. Calculate scores with my weights locally

Question:

Why did step 2. take hours to complete?

It seems like it's trying to connect to loads of relays.

My guess is either I am doing sth horribly wrong or there is no smart relay set calculation for filters in the pool.

In ndk this calculation takes under 10 seconds to complete, even without any caching. It will first look at the filters and calculate a relay set that has all authors in it then does the fetching.
