Kuba Suder • @mackuba.eu on 🦋Lulz, I've done some quick profiling now of my lib Skyfall reading from the Bluesky firehose websocket and just discarding packets, and it looks like as much as ~50% of time might be spent… converting an ascii string to a byte array on one level and then converting it back to an ascii string at the end 💀websocket-driver calls String#bytes first, and then I get a byte array from faye-websocket and I call pack('C*') on it to get a string… <a href="https://martianbase.net/tags/rubylang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rubylang</a>

Giacomo Suderi 🇮🇹🍝websocket-driver calls String#bytes first, and then I get a byte array from faye-websocket and I call pack('C*') on it to get a string to be passed to the CBOR decoder… if I can short-circuit that, then this might be a pretty good optimization 😅 <a class="hashtag" href="https://bsky.app/search?q=%23rubylang" rel="nofollow noopener noreferrer" target="_blank">#rubylang</a>

Todd A. Jacobs | Rubyist<a href="https://mastodon.au/@Linux" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@Linux</a> I do the same, but for topic focus. I use ruby.social for <a href="https://ruby.social/tags/RubyLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RubyLang</a> & other software- or developer-adjacent stuff; I post about <a href="https://ruby.social/tags/cybersecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cybersecurity</a> & non-dev <a href="https://ruby.social/tags/AI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AI</a> topics on infosec.exchange. I cross-link verifed accounts to assure followers they're all really me, but that's a personal choice.Who cares if you use multiple instances? Where's the harm? Some people need or want separate identities, or have other valid reasons. It's nobody else's business, really.

Peter SolnicaInteresting fact about <a href="https://hachyderm.io/tags/RubyLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RubyLang</a>, frozen empty strings and methods that operate on them, like byteslice in this example: it returns a new empty string instance!If your app allocates tons of empty strings, you could easily optimize it 🙂Things I learn when reviewing PRs in sentry-ruby SDK!

Christian Kohlmeyer<a href="https://mastodon.social/@caravana" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@caravana</a> Hm, that makes me think, cause my firts impression was, that languages like <a href="https://wehavecookies.social/tags/rubylang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rubylang</a> or <a href="https://wehavecookies.social/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> are a good start, but I agree with you after reading through it, with two exceptions:1) Performance is irrelevant from my point of view, when starting development as a beginner - success is more important 2) Algorithms can be learned also with python and might be even cleaner than in other languages. But I get your point: one might not try to understand basic stuff as e.g. sorting etc.

Kuba Suder • @mackuba.eu on 🦋Interesting… I've checked out of curiosity how this firehose client would run now with this new modern async-websocket lib from the "async Ruby" ecosystem, compared to the ancient eventmachine lib that I use in Skyfall (just reading packets), and… it seems to be slightly slower 🤔 <a href="https://martianbase.net/tags/rubylang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rubylang</a>

Kuba Suder • @mackuba.eu on 🦋Nice, I went from ~2k evt/s max to ~3.6k with a few fixes (partial index, ActiveRecord + <a href="https://martianbase.net/tags/rubylang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rubylang</a> update, YJIT on, batched saves in one insert, and matching using a <a href="https://martianbase.net/tags/rustlang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rustlang</a> module). One more thing to try (turning off Pg wal sync) :)The theoretical max possible would be ~5.5k, this is what it did on a test where it doesn't actually process anything, just reads from the socket. Although maybe the "async" lib would do better than eventmachine?…Though at 7.5k I hit the VPS bandwidth limit.
