TEST PURPOSES ONLY

this effects app launch time. i expected much more improvement but didnt happen :)

boost::json gave about %10 improvement

glaze not compatible with project because it requires C++20 and above

nlohmann parser

Total: 5400ms

load_system_presets_from_json
Time: 2605.42ms
load_presets user
Time: 2805.03ms

yyjson parser with string / operator optimizations

Total: 3890ms (%28 less)

load_system_presets_from_json
Time: 1914.75ms
load_presets user
Time: 1973.26ms

simdjson parser (first tests)

Total: 3770ms (%30 less)

load_system_presets_from_json
Time: 1857.21ms
load_presets user
Time: 1912.25ms

NOTES

• test made with all machines selected. orca loading only selected machines on start
• i left timers if you want to benchmark. set debug level to fatal for minimal log. search "Time: " on log
