+
+

Parse a dataset of 100 million page visits from CSV into a sorted JSON file using pure PHP. Each entry maps a URL path to daily visit counts, sorted by date ascending.

+ Rules + +
+
+

Solutions must be written in PHP only. No FFI, no external tools, no internet access. Your script may only work within the project directory.

+

The solution must validate against the real dataset. Improvements of 0.01s or more are counted. Ties are broken by submission time.

+
+
+
+
+ Server Specs + +
+
+

Mac Mini M1 with 12GB available RAM. JIT is disabled. OPcache is disabled.

+

Each submission is run individually on the dedicated server to prevent bias. Results are manually verified before benchmarking.
