莲花销售认为,电车特性就是加速快,但一旦到残血状态,加速能力会大打折扣。以特斯拉Model S Plaid为例,在20%残血电量以下,如果要达到官方标称的2.1s加速,需要预热至少1小时才可以。

there’s still work to do. the biggest gaps are SIMD prefilters for non-literal patterns - the dotnet version gets a lot of mileage from vectorized character class membership tests that we don’t have yet - and the bidirectional SIMD routines needed for our right-to-left scanning. pattern-specific optimizations like start-set inference and alternation simplification are also on the list. there’s also a lot of other low-hanging fruit - we don’t have any statistical optimizations yet, the Unicode classes could be baked in instead of constructing them while parsing, the memory usage could also be improved, there are many pattern-specific shortcuts we could add, and so on. but i hope the benchmarks show that it’s already competitive and useful in its current state.
