[#]Ruby perf question: What's the fastest way to iterate over segments in an HTTP route? (ex. "/users/:id/postst/:post_id")

I currently .split on "/" and call .each on the array. I thought I could avoid creating an array and perhaps gain speed by "consuming" the string directly. I tried three ways.

• Split a segment at a time.
• Use pointers to index over the string.
• Use String Scanner (regex).

The array is always faster. 🤔

Please boost to reach any big brains too busy to follow me. 😉
