q&#x2F;kdb+ is _enormously_ fast (or it was when I used it), but that was a result of 1) having a specific subset of problems to which the binary was highly tuned, 2) by Arthur Whitney who, in my mind, is one of those 100x engineers who was the key reason behind why it was so good as evidenced by 3) he&#x27;s no longer with them and as such you&#x27;ll notice an appreciable decline in code quality. I&#x27;m sure if AW was still working on the code-base, you&#x27;d be seeing a lot more AVX512 SIMD usage and clever things like that. (Take IDA to your q binary, it&#x27;s...acceptable but nothing magical like AW&#x27;s work. In fact, the lack of attention to detail is so significant the new engineers allowed even a poor rev. eng.[1] like myself to use a very <i>very</i> standard method to get a symbol table fully populated, confirming my suspicion that there&#x27;s very little platform specific code).<p>RE: 36MM - that makes sense. q&#x2F;kdb is the definition of &quot;low volume, high margins&quot;. You only have so many IB&#x27;s in Midtown, wealth management funds in Stamford, and a PIMCO here and there in Newport to shop your product to. (As opposed to say, Oracle, where there&#x27;s broad appeal, residual government contracts as a result of legacy PL&#x2F;SQL code from 20 year old code that&#x27;s kept in production.)<p>[1] E-mails in the profile if you want to hear how I got a symbol table in, but I&#x27;m sure you already guessed by now.
