as someone that has written way too many ruby DSLs i would say use ERB. it's easy to read for non-ruby experts, fast, built-in, and has good editor support. can't really do better than that....

I'm profiling some code to try and squeeze out performance. It takes a user query, reads data from the database and returned the result as XML

I have tuned the code and database (checking the indexes, caching repeated calls etc) and what I am left with is that 95% of the call's runtime is building the XML. We are using builder because it is the standard / default for Ruby

Using Ruby 3.0.2p107 as it is the default for Ubuntu 22.04

Is there another, faster library for XML generation or will I be building this by hand?

Any suggestions
