Performance improvements?

@crocodele I was wondering if you've seen any preliminary improvements in performance/resource usage by using this extension in your applications over PHP-based implementations?
@mkaminski1988, sorry for the long response time. We haven't plugged the extension into our applications yet – I will do that when we have the extension in a stable state that we know is free from segfaults and memory leaks. Not far away now. 🙂 But I have run one benchmark with a huge JSON file (200k rows, filesize 180MB), comparing the extension against a userland-PHP library as well as library-less array traversing in PHP. The results there are:
- extension: 0.11 seconds
- library-less traversing in PHP: 0.93 seconds
- userland-PHP library: 4.1 seconds
I expect the differences to be smaller for smaller datasets, but the above is pretty impressive nevertheless!
My intention is to create a benchmark suite with small, medium, and large datasets as well as simple and complex JSONPath expressions (and the equivalent library-less PHP code).
Awesome, thanks!
