  1096 \textbf{Re: Another question of purely academic interest about regex implementation in cw3}

  1097 

  1098 This conversation is interesting to me, and I've researched it a

  1099 little bit [...] I also disagree with Dr.~Urban on the cost/benefit of

  1100 non-GC languages [...]\smallskip

  1101 

  1102 But regardless, Scala is a lot slower than, say, C or Rust. To say

  1103 it's not is basically wrong (imo). Perhaps one could argue that some

  1104 of the guarantees Scala has makes it easier to write multi-threaded

  1105 programs that utilise more of the CPU... but, in my opinion, this is

  1106 also a bit misleading. Most CPUs have something like 4 to 12 cores

  1107 nowadays. It's very possible that a given Scala program runs 4-12x

  1108 slower than its Rust equivalent. Would you rather have your program

  1109 run quickly and use a single core, or have it run equally

  1110 quickly... and... hog your entire CPU for its duration?\ldots{}
