| | | | | | | | | | | | | | | | | | | | | | | | | | | * Memory mapped file, single-pass parsing, custom hash map, fixed thread pool The threading was a hasty addition and needs work * Used arraylist instead of treemap to reduce a little overhead We only need it sorted for output, so only construct a treemap for output * Attempt to speed up double conversion * Cap core count for low-core systems * Fix wrong exponent * Accumulate measurement value in double, seems marginally faster Benchmark Mode Cnt Score Error Units DoubleParsingBenchmark.ourToDouble thrpt 10 569.771 ± 7.065 ops/us DoubleParsingBenchmark.ourToDoubleAccumulateInToDouble thrpt 10 648.026 ± 7.741 ops/us DoubleParsingBenchmark.ourToDoubleDivideInsteadOfMultiply thrpt 10 570.412 ± 9.329 ops/us DoubleParsingBenchmark.ourToDoubleNegative thrpt 10 512.618 ± 8.580 ops/us DoubleParsingBenchmark.ourToDoubleNegativeAccumulateInToDouble thrpt 10 565.043 ± 18.137 ops/us DoubleParsingBenchmark.ourToDoubleNegativeDivideInsteadOfMultiply thrpt 10 511.228 ± 13.967 ops/us DoubleParsingBenchmark.stringToDouble thrpt 10 52.310 ± 1.351 ops/us DoubleParsingBenchmark.stringToDoubleNegative thrpt 10 50.785 ± 1.252 ops/us | ||||
