That kind of performance just doesn't matter that much though. I recently benchmarked my fairly standard Rails app on 1.8.7 vs. 1.9.2, and the numbers for delivering a page are basically the same.
1.9.2 is much faster for calculating Fibonacci numbers, sure, but since webapps are mostly IO bound it just doesn't matter.
- troels 16y agoOh - I fully agree. For most situations, raw computation is irrelevant. But even in the cases where it matters, PHP isn't remarkably faster than its closest alternatives.
- igouy 16y agoWho's shown Fib? If "it just doesn't matter" then what's the point of 1.9.2 performance improvement?
- towelrod 16y agoThere's not much of a point -- that's why 1.8.7 is still around, and why uptake on 1.9.2 has been so slow. If 1.9.2 really made every HTTP request go 2x as fast, don't you think every Ruby shop would have switched to 1.9.2 at least a year ago?
