If you want to compare it against other languages you could look at The Computer Language Benchmarks Game [1], which is an ongoing comparison of various programs written in various popular languages. You should always take all these benchmarks with a pinch of salt though since they are never truly apples-to-apples. That said, Ruby seems to measure slightly faster than Python and Lua, slightly slower than PHP, and maybe 1 order of magnitude slower than Node.js, just to compare it with other similar languages.

Compared to itself from 10 years ago I think it's made great progress. Can't put a number to it but I wouldn't be surprised if it's 2x or 3x faster, especially with the "new" JIT (YJIT) enabled. The JIT comes with a memory usage penalty though. You can see some benchmarks over time (although not going back as far as 10 years) at https://speed.ruby-lang.org
