I ve managed a slight improvement from native python , and a pretty good improvement over my initial pyrex module 我已经对原有的python进行了一些细微的改进，这可以稍微提高最初的pyrex模块的速度。
For example , the pyrex home page prominently features a numeric - intensive function for calculating a list of initial prime numbers 例如， pyrex主页上使用一个计算素数列表的数学函数来宣扬这个特性。
Gaining a few percent in speed differs from gaining 40 times like the pyrex home page - and many pyrex users - boast about 速度提高几个百分比和pyrex主页（以及很多pyrex用户）那样提高40倍有很大的差距。
