Test & Performance

run Test in Example demo

test and performance under

• Apple Swift version 4.0.3 (swiftlang-900.0.74.1 clang-900.0.39.2)
• Target: x86_64-apple-macosx10.9

for example, with amount data, every time add some data into it, take its minimal preifx count, the amount, additional data count, preifx number are keys for sorting efficiency.

with amount:256 addition:512 prefix:16 loop:10
