        Great post. Totally agree that perf can be a feature. But would you have 1) known to value instant response time and 2) been able to convince people its worth the investment if you didn’t have the previous experience of a poorly performing static analysis tool?

        Parser is an amazing gem and we got and get a ton of value out of it, I don't want to shit talk it at all. But yeah the comparison is stark :/

        > attempts to add performance to a slow system often add complexity I've seen this first hand, but never heard it mentioned before. I like this article a lot, its a really well rounded and considerate take on the subject, thanks for taking the time to write it down.

        Excellent article ! Thank you for this, wording my thoughts that I don't achieve to communicate around me clearly. Will share! To answer the las question: Everything Engine. A must-have on Windows, where the first feature IS performances.
